How would removal of 95 percent of the stomach to treat severe ulcers or cancer affect the digestion and absorption of food?
The stomach stores food and released small amounts regularly into the intestines for digestion. If the stomach was removed the patient must eat small amounts of food regularly. If they ate a normal sized meal it passes into the intestine and due to osmosis, a great deal of water moves into the intestines - 'dumping syndrome' which can cause nausea, diarrhoea, bloating, cramps, fatigue and dizziness. It would also affect blood sugar and could cause hypoglycaemia. So removal of the stomach makes digestion and absorption much more difficult.The stomach lining cells also produce Intrinsic factor which is needed for the absorption of vitamin K. Therefore the patient may become deficient in vitamin K.The job of the stomach is to break down proteins, mix and begin digestion. It is not involved in the absorption of food. If a person has a small stomach, they will loose weight but the stomach can stretch and enlarge.
What would happen if you didn't have you stomach?
You can survive without your stomach. There are three main digestive organs...the mouth, stomach and small intestines. Without the stomach, you may have to eat smaller amounts at each sitting or you may have to adjust what you put into the system, but your body can still do some basic digestion and the bulk of the absorption of the food.
What part of the gastrointestinal tract is responsible for 90 percent of nutrient absorption?
The lining of the small intestine is covered with tiny projections with many capillaries. The projections are called villi. Nutrients pass into the capillaries of the villi and then to other organs of the body.
What are the organs of the digestion in order that the food passes through?
The mechanical process of digestion is first, followed closely by chemical digestion. After that it is mostly chemical digestion, then absorption, and lastly elimination, or defecation.
What does not occur in the nasal cavity?
The process of digestion does not occur in the nasal cavity. The nasal cavity is responsible for filtering, warming, and moistening the air we breathe, but it does not play a role in the digestion of food. Digestion primarily occurs in the gastrointestinal tract, starting from the mouth and continuing through the stomach and intestines.
Where in the body is chemical digestion and absorption of nutrients completed?
Small and Large intestines
Although the stomach is responsible for digestion very little occurs in it?
Absorption
Is the stomach the first site where absorption takes place?
No it is not, the stomach initiates protein digestion and denatures proteins. The intestines is the first site where absorption takes place.
What organ does most digestion take place?
Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
What occurs in the stomach although it is responsible for very little digestion?
Although the stomach is responsible for digestion, very little absorption happens in it. Instead, the stomach is more like a washing machine; it agitates foodstuffs. It stirs up ground up food (mechanical digestion from teeth / gums occurs in the mouth), with stomach acids in the stomach and bile salts from the gallbladder assisting in chemical digestion.
Is The stomach is responsible for digestion and all absorption occurs there?
This is not true. Almost all absorption occurs in the small intestine. The stomach simply uses its enzymes to break down food into smaller and smaller molecules. The most mechanical digestion occurs in the stomach due to the constant churning motion.
What function does hydrochloric acid serve in digestion?
Hydrochloric acid helps digest and soften food for absorption into the intestines. Hydrochloric acid is, essentilally, your stomach acid.
What is primary absorption?
If your asking about primary absorption in digestion and the absorption of nutrients into the body, then primary absorption is the first (primary) place in the body where nutrients are absorbed. In humans this takes place in the small intestines after the food has been broken down in the stomach and passed on to the small intestine.
What is the location where the majority of the digestion and absorption occurs?
Most of digestion occurs in the stomach and most absorption occurs in the small intestine.
Can the digestion be done in a different place than the stomach?
in the small intestines and the large intestines
What are major organs for digestion?
Liver, pancreas, intestines, stomach.
Where organ did most of the digestion take place?
intestines and the stomach.
