What will happen if large intestine will not be able to reabsorb water from digested food?
you will develop diarrhea.
They feed on digested food in your large intestine and anus.
Why enzyme pepsin works only in the stomach?
Protein digestion occurs in stomach only because it is safe for the body, as stomach has mucous secretions which prevents self digestion of stomach muscles by PEPSIN (enzyme for protein digestion) :)
Which organ make up the digestive system?
The major organs of the digestive tract are:
-Mouth/Teeth
-Esophagus
-Stomach
-Small Intestine
-Large Intestine
-Rectum/Anus
The digestive system also has organs that food does not go through. These organs include:
-Liver
-Gallbladder
-Pancreas
What animal has the digestive system of a carnivore but is actually vegetarian?
As found on http://www.ypte.org.uk/animal/panda-giant-/157, Pandas spend 2/3 of their life eating because they are ill equipped to properly digest the bamboo they favor. They are, natural carnivores, who are too slow to catch prey and have "chosen" to eat bamboo instead, making them functional vegetarians, rather than obligate vegetarians.

What is the similarities between the digestive system of a bird and a human?
Humans and lions are both mammals.
Characteristics of mammals are:
All mammals reproduce by giving birth to their young.
All mammals feed their young ones with milk.
All mammals have hairs on their body.
Therefore if the two are classified in the MAMMALS section so their bodies must be the same.
From my opinion humans and mammals have the same digestive system.
Humans and mammals can't have the same digestive system as humans eat plants (we are omnivores) and lions eat meat (carnivore). Therefore we have different digestive needs, our intestinal tract would be longer than that of any carnivore (so we can get the most nutrients out of the food we eat, whereas a carnivore needs a shorter digestive tract so the meat doesn't go rotten inside it's intestine).
Seriously think about it, cows are mammals as well but they have four stomachs (because they are herbivores)!
What type of digestion system does a pig have?
The main functions of the fetal pigs digestive system is to digest food, absord nutrients, and excrete waste.
What is the correct sequence for the passage of food through the human digestive tract?
First, the food enters through the mouth and food is masticated and chewed, while oral juices secreted by oral glands are mixed by the tongue. This juice contains salivary amylase, which primarily breaks down carbohydrates, in forms of sugar and starch, and mucin, which lubricates the food in order for it to go smoothly down the esophagus. After being swallowed, it will roll down to the pharynx, which separates the passageway for food and air. We sometimes choke when food enters the wrong passageway, that is, in the event that food goes down the trachea, or the windpipe. The initial reaction to this is to choke. When food goes into the right path, we go to the esophagus, which us a muscular tube that leads to the stomach. The lubrication of the food by the mucin of the saliva and the peristalsis (wave-like motion of the esophagus to assist the food on going to the stomach smoothly) helps for it to reach the stomach quickly. The stomach is the first chamber of chemical and physical digestion for the food. Internal folds inside the stomach called rugae help in grinding and breaking down the food while the stomach churns. That is the physical digestion part. The chemical digestion kicks in when the gastric juices, secreted by gastric glands found inside the stomach, break down the food. Some of these gastric juices are gastric amylase, which break down carbohydrates, trypsin which breaks down proteins, and lipase which breaks down fat. The technical term used to refer to the food broken down in the stomach is chyme. The chyme, then, is regulated by the phyloric sphincter, a valve which regulates the amount of chyme entering the small intestine. The small intestine is where most of the chemical digestion and absorption occurs. The accessory digestive glands help by secreting juices, such as bile, some hydrochloric acid (HCl) and other enzymes. The nutrients are "absorbed" by finger-like projections called villi. What actually happens, is that the villi contain capillaries, very thin blood vessels, so thin, that red blood cells need to pass through a single file to fit; these capillaries are where the nutrients from the food digested diffuse into. These capillaries then lead to larger blood vessels, and the nutrients are sent to cells via the blood. Now that the essential materials are distributed, the "leftovers" are sent to the large intestine, where water diffuses into capillaries, and some essential materials not absorbed in the small intestine. What is left is waste, then sent to the rectum, which is a temporary storage of feces. When the rectum is a bit full, the waste will exit the body through the anus, and that is feces.
That is what I know of the digestive system. Hope it helped!
Good luck! ;]
Why is the appendix known as vestigial?
Because it no longer serves any useful purpose. It can be removed, without the body suffering any deterioration from its loss.
Why is the saliva in your mouth an example of enzyme?
im trying to figure that out
-_-ya i know your probely mad that i wont answer your question huh?
Is a human appendix a homologous structure?
The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.
What nutrients break down in the stomach?
Proteins are digested in the stomach. Pepsin is the enzyme, which is responsible for breaking the peptide bond of the proteins.
Is this True or false digested food is absorbed through the large intestine?
False. Food is digested and absorbed in the intestines. The stomach assists with breaking down chemical bonds the food is comprised of and allows for absorption and distribution of nutrients. Undigested particulate matter is passed through the intestines and is known as feces.
How is digestion a series of chemical reactions?
Digestion is a series of chemical reactions because the food is broken down and changed in physical properties and made into nutrients for the body to use as energy.
How does flu affect the digestive system?
In extreme cases, all of them.
The center of the swine flu viruses' attack is the respiratory system. Depending upon the degree of oxygen deprivation this might cause in the severe cases, all other systems can be affected by this lack of oxygenation. Some people get gastrointestinal symptoms and with fever, some, especially children can suffer seizures indicating an involvement of the neurological system. Dehydration from nausea and vomiting is often the first problem manifested that cause people to seek hospital care, and it can create problems with the kidneys and urinary and fluid balances. This can also cause ramifications with the circulatory system and heart. The immune system is affected as it attempts to attack the virus.
The most common cause of death is fluid in your lung and dehydration. The first reported death was from fluid-filled lungs. Pneumonia is one of the major complications in severe cases of the pandemic flu. It can be viral pneumonia, or it can be caused by a secondary bacterial infection.
What is the smallest organ in the digestive system?
The Epiglottis is the smallest part to the Digestive System
To turn food into smaller molecules so that food can be absorbed and later turned into energy for us to use.
What chemical compound is found in all indigestion tablets?
magnesium hydroxide or calcium hydroxide.
-------
Indigestion tablets (antacids) may contain: CaCO3, MgCO3, Al(OH)3, Mg(OH)2, NaHCO3, KHCO3, etc.
All these substances dissolved make an alkaline solution - to neutralize the excess of hydrochloric acid from the stomach and to control of the gastric pH.
What do you call the rounded mass of food prepared by the mouth fr swallowing?
its still called food.
How does the digestive system absorb nutrients?
Well to understand how our bodies are capable of digesting plants we must familiarize ourselves with some of the major organs that are responsible for providing the proper enzymes. One of the most commonly misunderstood factors is that the stomach cannot digest the cellulose in plants. However, this should not be misinterpret as not being able to digest vegetables.
First the saliva glands releases enzymes that bind to the food as it goes down the esophagus. Then in the stomach lining, other enzymes called stomach acids are released to break down proteins. However, since plants have a very strong cell wall, the enzymes can barely take anything off the external layer but can only separate each cell from binding which allows them to pass into the pancreas which produces a juice that further shrink the cellulose, although it does not destroy them but only shrinks them further to have them absorbed into the the blood stream. Those that did not get separated go out in waste. In the blood stream, the cellulose stays intact while scraping off unwanted cholesterol as it travels. At this point, the plant cells have become much weaker than when they were in the stomach and are all flowing independently. Finally, the cholesterol and the plant cells go through the liver where they are destroyed by the liver's enzyme called the biles. Biles are enzymes that are far more powerful than the stomach acids and they dissolve even cellulose.
What contains an enzyme that starts the chemical digestion of food?
saliva is the substance in the mouth that contains enzymes to help with digestion before the food is swallowed.
