What organs are in the digestive systum?

By far, the largest organs in the digestive system are the small and large intestines. The small intestines is bigger (longer) though. The smallest organ or muscle is the tongue! The smallest item involved in mechanical digestion is the teeth!

Can you burn out a pancreas?

If the pancreas was to brust i really dont know what would happem..

The digestive system organ that passes waste to be excreted and reabsorbs water and minerals is the?

LARGE INTESTINE, its main functions is to absorb water and electrolytes from digested mass, resulting in semi solid feces

How can the parts of ahuman body digest system help to break down molecules of fat?

Fat is first processed by a mechanical breakdown in the mouth through chewing and in the stomach through its ‘churning’ action. Lipase, an enzyme produced in the pancreas, converts fat in the small intestine into fatty acids and glycerol. Chewing helps to increase the surface area of food and hence increase the rate of this breakdown. Bile acids, which are produced by the liver, aid this process by emulsifying the fat (further increasing surface area) and by packaging the fatty acids and glycerol into small, water-soluble molecules which can be absorbed by the small intestine. Bile also helps to neutralise the acid from the stomach, reducing acid reflux and producing alkaline conditions in the small intestine where the fat is being broken down and absorbed

What is the purpose of digestive enzymes?

Digestive enzymes are enzymes that break down polymeric macromolecules into smaller building blocks. This is done in order to help facilitate their absorption by the body.

What may happen to the food we eat when large intestine is not working well?

If it stays in the large intestine for too long your stool will become hard and you will find it hard to pass through. We call this constipation. And if it doesn't stay in the large intestine long enough the water in your stool won't have been absorbed into the body and you will have diarrhea

What is the meaning of a digestive system?

Digestion is the breaking down of chemicals in the body, into a form that can be absorbed. It is also the process by which the body breaks down chemicals into smaller components that can be absorbed by the blood stream. There are also digestive system disorders. Read about them on the internet for more info.

Does LSD have any physiological effect on the digestive system?

LSD is taken by letting it diffuse through thin skin under the tongue right to the blood stream, it ommits the digestive system. Swallowing/drinking LSD would destroy the LSD molecules because of highly acidic ph of stomach. LSD mostly focuses on serotonin receptors in the brain, but the scope of receptor types affected by this drug is enormous and the only way I can think of for LSD to be harmful to digestive system is through some highly complicated endocrine pathways in regular users, but it may have no effect at all.

Do all herbivores have an appendix?

The appendix is found in higher apes, wombats, opossums, rabbits, some rodents, and a few lower mammals. So, no.

Does the circulatory system transport carbon dioxide away from the cells?

The respiratory system does "take away" carbon dioxide by replacing it with oxygen, through breathing. Exhaling causes the body to expel carbon dioxide and inhale oxygen.

What is located in the villi that line the small intestine that absorbs fats and fat-soluble vitamins?

Fats are absorbed by entering the villi and then breaking down into a chemical compound or ester called chylo microns which are made fron lipoproteins(fats and proteins) and tryglicerides(compound of fatty acids and a glycerol molecule)

How much does the average person in the west excrete per day?

It's normal to defecate once and urinate six to twelve times, depending on fluid consumption and caffeine intake, etc.

Why is Bicarbonate is released into the duodenum during the process of digestion?

The statement that bicarbonate is released into the duodenum during the process of digestion is true. The Brunner glands in the duodenum secrete mucus that contains sodium bicarbonate which neutralizes the acid in chyme thereby protecting the duodenum.

Is excess water reabsorbed from the small or large intestine?

The small intestine absorbs food and the large intestine absorbs water.

A food chute has no digestive or absorptive role?

The esophagus.

gullet=food chute. it does not digest things or absorb nutrients and goodies and stuff

What organs are part of the digestion system?

mouth-chew in the food the saliva get it moist it turns to a ball

Why are digestive enzymes are called hydrolases?

Any enzyme that uses hydrolysis (break a molecule in two, break H2O into OH- and H+, match one ion with one piece of molecule, result in two smaller molecules) is called a hydrolase. In chemical digestion, hydrolysis is the main chemical reaction used by the enzymes to break proteins, lipids, carbohydrates, and other complex molecules into smaller pieces.

Why are the three parts of the large intestine called ascending transverse descending?

It has to do with the direction the waste travels in. Ascending is the section of bowel (large intestine) where waste travels up the intestine, transverse is the section that goes across the middle of your body and descending is the part that flows down toward the colon ready for excretion through the rectum and anus.

Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells?

it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
