Digestive
Question: How does the digestive, circulatory, and respiratory systems work together? This is for a science project due tomorrow, I have the main part done but I'm having trouble answering these questions:
How do the digestive and respiratory systems work together?
How do the digestive and circulatory systems work together?
How do the respiratory and circulatory systems work together?
Answer: Digestive and respiratory work together because the lungs and will supply the blood with o2 and that will travel threw the circulatory system via arteries, veins, and capillaries. the o2 can then be absorbed in the muscles used in the digestive system to break up food and use it for energy.the circulatory and repertory work together to supply the body with o2 and to remove co2. the lungs will take in o2 and will go into small tubes called bronchioles. these will then connect into aveoli then to capillaries. the capillaries then transfer the 02 into the heart to pumped throughout the body. hope this helps good luck
Question: What are some differences between the human digestive system and the pig digestive system? Same as above what are some differences between the human digestive system and the pig digestive system?
THANKS!
Answer: for one thing the pig has a much more resilient digestive system - it can eat it;s own excrement with no ill effect. It can eat carrion that would kill a human.
Question: how does the digestive system work in relation to energy metabolism? how does the digestive systmem contribute to getting energy in the body?
Answer: 1 The digestive system is the group of organs that breaks down food so that the body can use it. Food must be broken down all the way to its individual molecules to be useable. This involves a number of steps, and different organs to do different parts of the job.
2 Once food is broken down it provides energy for many essential body functions. It provides the energy for all of our physical activity such as walking, playing sports, working, and talking. It also provides the energy for other, more automatic, activities including breathing and thinking. Food provides the energy for the nerves, muscles, and organs, including the heart, to continue working. It provides the fuel to build and repair body tissues. Food energy is needed to regulate body organs and systems. It is the fuel that provides heat to keep our body temperature at a steady 98.6 degrees.
3 The digestive process begins in the mouth. There, the teeth and the muscles of the mouth begin the digestive process by breaking down the food into smaller bits. Saliva, produced by the salivary glands, begins to digest the food before it is even swallowed. Saliva and the other chemicals produced along the way to speed the digestive process are called digestive enzymes
Question: How do the digestive system and the circulatory systems depend on each other? How do the digestive system and the circulatory systems depend on each other?
Answer: Basically, the digestive system receives nutrients from foods, and converts it into sugars and proteins that the circulatory system can transport to the various organs and tissues in your body. However, your entire body, and all the cells in it, depend directly on the circulatory system for nutrients, and the circulatory system depends directly on the digestive system for nutrient absorbtion.
Question: What nutrients are digestive enzymes made of? I've heard that digestive enzymes are made out of amino acids but aren't they also made out of other nutrients such as vitamins or minerals? -iron maybe? Please clarify.
Answer: Enzymes are biological catalysts. Their purpose is to change the rate of a chemical reaction. Often, without the enzyme present, the reaction would be so slow as to not occur at all under normal conditions.
Like all proteins, enzymes are made from strings of amino acids folded up into an intricate three-dimensional structure. Amino acids may be composed of several elements, including nitrogen, carbon, oxygen and hydrogen.
Your body can synthesise some amino acids from scratch, but the 'essential amino acids' can only be recovered from food you eat. The proteins you consume are broken down into constituent amino acids in the digestive system by enzymes and recombined into new proteins for use in the body's tissues.
Some proteins, including some enzymes, do need elements such as iron to function. Haemoglobin, for example, is used in blood to transport oxygen. Each molecule has several iron atoms in its structure.
Question: What kind of digestive and bowel problems can you have with diabetes? What kind of digestive and bowel problems can you have with diabetes?
I have the added complication of Spinabifida, which makes it hard for doctors to work out what is happening.
Answer: Diabetes may affect the autonomic nervous system and as a consequence may affect the function of the gastrointestinal tract. This is most true the longer you are a diabetic and if your diabetes is not well controlled. The esophagus may suffer from poor motility meaning that food may not pass easily into the stomach. The stomach may empty too slowly which is called gastroparesis. The small intestine may fail to produce incretin mimetics and may also lose the ability to add ''water' to the contents of the food after it has left the stomach. Such fluid is necessary for proper absorption of nutrients. The colon or large intestine may also lose it motility leading to constipation. There is also a condition known as 'dumping syndrome' which involves faulty communication between the stomach and the colon. If I may be of further assistance please let me know. I wish you the very best of health and in all things may God bless.
Question: What order does food travel through the digestive system? I know the digestive tract is the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and the anus.
But what exact order does the food go through? It it the same as the digestive tract?
Answer: I'd say that the digestive tract was the name for the more-or-less tubular organs through which food travels. The digestive SYSTEM includes a few more things, like the liver, gall bladder, salivary glands, etc., which may be involved in digestion but not in direct contact with food. If you're tracing the path of food, you've listed the correct order in your question.
Question: How is cheese pizza digested through the digestive system? . Think about a slice of cheese pizza. Starting at the mouth, trace the path that the pizza will take through the digestive system. Explain what is happening to the pizza at each step, matching the key digestive processes with the 3 main components of pizza: crust, cheese and sauce. Describe when, where and how each component is digested.
Answer: Sorry... This is kinda long, because it's very detailed.
This is the general idea of the complete digestion in the body. In this case, just subsitute 'pizza' in it.
The Mouth:
-----------------------------------
The process of mechanical digestion begins as you take your first bite of food. Your teeth carry out the first stage of mechanical digestion. Your centre teeth/incisors, cut the food into bit-sized pieces. On either side of the incisors are sharp and pointy teeth called canines. These teeth tear and slash the food in your mouth into smaller pieces. Behind the canines are the premolars and molars, which crush and grind the food. As the teeth do their work, saliva mixes with the pieces of food, moistening them into one slippery mass.
When you eat a candy, it tastes sweet. It does because a chemical in the saliva has broken down the starch in the candy into sugar molecules. The breakdown of complex molecules into simpler ones-has taken place. This is called chemical digestion, and it is accomplished by enzymes.[A protein that speeds up chemical reactions in the body]
-----------------------------------
The Esophagus:
-----------------------------------
As you swallow, muscles in your throat move the food downward. While this happens, a flap of tissue called the epiglottis seals off your windpipe, preventing the food from entering. After that, food goes into the esophagus, a muscular tube that connects the mouth to the stomach. The esophagus is lined with mucus. Mucus is a thick, slippery substance produced by the body.
Food only remains in the esophagus for about 10seconds. After food enters the esophagus, contractions of smooth muscles push the food toward the stomach. These involuntary waves of muscle contraction are called peristalsis.
--------------------------------------…
The Stomach:
--------------------------------------…
Food enters the stomach after it leaves the esophagus. Stomach is a J-shaped, muscular pouch located in the abdomen. As you eat, your stomach ach expands to hold all of the food that you swallow. An average adult's stomach holds about 2-2.5 litres of food.
Three strong layers of muscle contract to produce a churning motion. This action squeezes the food, mixing it with fluids.
The churning of the stomach mixes food with digestive juice, a fluid produced by cells in the lining of the stomach. Digestive juice contains the enzyme pepsin that breaks down proteins in your food into amino acids. Hydrochloric acid keeps the stomach functioning properly: keeping the stomach an acidic environment→1. Pepsin works best in an acidic environment. 2.→ This very strong acid kills many bacteria that you swallow along with your food.
Food remains in the stomach until all of the solid material has been broken down into liquid form. Proteins will be chemically digested into chains of amino acids. The food, now a thick liquid, is released into the next part of the liquid, is released into the next part of the digestive system→ That is where final chemical digestion and absorption will take place.
--------------------------------------…
The Small Intestine:
--------------------------------------…
After the thick liquid leaves the stomach, it enters the small intestine. It is at about 6metres. It makes up 2/3 of the digestive system. It is called 'The SMALL Intestine' because it has a small diameter→It is only about 2-3 centimetres wide.
As the liquid moves into the small intestine, it mixes with enzymes and secretions. They are produced by 3 different organs→The small intestine, the liver, and the pancreas. The liver and the pancreas deliver their substances to the small intestine through small tubes.
The liver produces bile→which breaks up the fat particles. Bile flows into the gallbladder, storing bile until the small intestine needs it.[Bile is not an enzyme, because it doesn't chemically digest foods. It breaks up large fat particles into smaller droplets]→The droplets will be digested by enzymes produced by the pancreas.
The small nutrient molecules are ready to be absorbed by the body. Millions of tiny finger-shaped structures absorb nutrient molecules. Nutrients pass from cells on the surface of a villus into blood vessels.
--------------------------------------…
The Large Intestine:
--------------------------------------…
By the time material reaches the end of the small intestine, most nutrients have been absorbed. The remaining material moves from the S.I. into the L.I.. The large intestine is the last section of the digestive system. It is about 1&1/2metres long. The L.I. contains bacteria feeding on the material passing through. The bacteria normally do not cause disease. They are actually helpful because they make certain vitamins, including vitamin K.
The material entering the L.I. contains water and undigested food such as fibre. As the material moves through the L.I., water is absorbed into the bloodstream. The remaining material is readied for elimination from the body.
-------------------------------
The large intestine ends in a short tube called the rectum. Here waste material is compressed into a solid form. This material is eliminated from the body through the anus, a muscular opening at the end of the rectum.

Question: Can your digestive tract speed up during pregnancy? I've been having a lot of lower digestive problems, like (excuse me for being icky) diarrhea and stuff. Havent changed my eating habits or anything and I was wondering if being pregnant can speed up your digestive tract. I know it can slow it down and make you constipated but can it speed it up?
Answer: It's not necessarily that your digestive tract speeds up but typically due to hormonal changes, you'll get diarrhea during pregnancy. I've had more of a problem with diarrhea than I have constipation. Any time you have a surge in hormones that your body isn't used to, diarrhea can be the result. I remember when I stopped taking birth control last year, I had severe diarrhea for about 2 weeks. It was just because of the hormone swap. You're welcome to take Immodium during pregnancy if you need to. If your diarrhea is severe, you need to see your doctor to make sure you don't get dehydrated. Good luck!
Question: How can I cleanse my digestive system after eating junk food? I ate a lot of junk food last night, and I want it out of me as soon as possible, since I'm usually a healthy eater and I exercise daily. Is there some kind of over the counter medicine that can sort of reset/cleanse the digestive process? Thanks.
Answer: Whatever you do, don't go for the "colon cleansers" that are out there. They are frauds, and will make you unhealthy in other ways by messing up your internal flora. No real doctor has ever agreed that they work and are a good thing.
The best way to clean out your colon the natural way and the way that it was meant to be cleansed is to drink lots of water, and eat food with lots of fiber such as whole grains and fruits and veggies.
Also, this may be my personal opinion, but one night of eating junk food won't do you any harm if you eat healthy and excercize regularly. You might be getting a little OCD about this. You feel that by eating it you ruined your healthy diet and screwed up your junk-free system. The reality is, you didn't, so don't worry. It takes months of eating junk food regularly to build up in your system where you need to "reset."
Question: What is the best way to regulate your digestive system? My digestive system is irregular and I've tried benefiber and other fiber supplements and it helps, but it doesn't completely regulate it. Is there any other way I can completely regulate my irregular digestive system?
Answer: Some rules I try to follow:
Try to avoid doing shiftwork. It's much easier to keep your digestive system regular if you work a 9-5 job - if you have a regular routine your body will too.
Don't eat later than 6pm (or at least 3 hours before bedtime), so as to ensure you don't go to bed on a full stomach.
Eat fiber for breakfast, but never mix carbs and protein. Your body digests carbs well, it also digests protein well but for some reason it is less efficient at digesting them both together. Look at 'The Hay Diet' (Google it). It really helps me!
You must drink enough water. At least 2L a day.
Try to avoid caffeine, especially in the afternoon/evening.
Try to get some exercise.
Question: How do you make an artificial digestive system? For science we have to bring in food and build an artificial digestive system to break it down. Thing is, we have to keep the nutrients the food provides. Any suggestions?
Answer: The system is able to animate the growing processes based on stored information about the known movemets and based on several known development stages will be developed. Preliminary, the system will be filled with the data of human embryo digestive systems at different time steps of development. Later this model can be extended to include other related organs like liver and pancreas.
The anatomists and students will understand the development process accurately and will be able to explore the digestive system at various stages of human embryo development. The processes not saw before will be easily manipulated in large scale.
Finally, the system will be used practically in Department of Anatomy, School of Medicine, Hiroshima University in Japan for testing of drugs that partially control the growth of tissue.
I believe that the undesired growth of an organ will be located and observed easily than in recent time.
THis is against Nature,... CRap THEORY
Question: What is the digestive system for sugar gliders? I'm doing an assignment on the Sugar Glider, but i can't find it's digestive system! Does anyone know what their digestive system does and how it operates?
Answer: It'll be the same as other members of the Family, so don't worry about the specificity of the species.
Actually, here is an article that be of some help:
http://www.ncbi.nlm.nih.gov/pubmed/19341949?ordinalpos=2&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum
Question: What do you think is the effect of the digestive enzyme on the hard egg white? Have you tried this kind experimentation? Can you describe the hard egg white when it is mixed with the digestive enzyme in water?
I did an experimentation on this and I used Maalox as a digestive enzyme and I don't see any effect.
Help pls.
Answer: maalox is an anacid not a product that contains enzymes. This experiment (when done with an enzyme) should breakdown the egg white. Seach "egg white digestive enzymes" but do an advance search and click on .edu sites only. That should answer all you questions
Question: What is the process of the digestive system of a frog? I really need help with this assignment, i need to know the processes of the digestive, respiratory and circulatory systems?
Please help!
Answer: http://en.wikipedia.org/wiki/Frog#Respiration_and_circulation
Good to have this site
Question: How is Circulatory system and the digestive system related? I am doing a project worth quiet a bit of my grade. I need to explain a connection between those as well as these questions. How are the respiratory and Circulatory system related, and How is the respiratory and digestive system related.
Or any Connection you can think of for Animal Anatomy and Physiology. Any help would be great. Thanks
Answer: when you breathe in, your lungs fill with air. your circulatory system runs around all of your body, including your lungs. the hemoglobin proteins in your bloodstream pick up the oxygen from your lungs, and that hemoglobin-oxygen complex (called oxyhemoglobin) dumps off the oxygen to all the other parts of your body. now that blood has no oxygen, and must be pumped back over to the lungs, via your heart.
and for the digestive system, your small intestines folds up on itself a bunch of times to give itself more surface area to absorb more nutrients. on each of the folds are tiny little "fingers" called villi which are what actually absorb the nutrients, and there's even microvilli on top of the villi. the bloodstream runs through the villi and the nutrients get transported into your bloodstream
