Where in the body are the majority of nutrients absorbed into the blood?

Question

Is it the stomach, or one of the intestines. I'm thinking intestines.

Answer 1

sm. intestines

Answer 2

Starches begin breaking down right away because there are enzymes in saliva to do this. The stomach acts as both a storage place and also a barrier to infection. The strong stomach acid kills most bacteria. It also can soften things like small bones.
Fats and fat soluble vitamins cannot be aborbed until they are separated into very tiny droplets. This happens in the first loop of the small intestine with bile secreted from the liver. There are also enzymes secreted from the pancreas that begin breaking down proteins. So, as people have mentioned, absorption into the blood stream occurs in the small intestine. Extra water that was put into the stomach and early in the small intestine to help dissolve food is then reabsorbed in the large intestine. However, if you are dehydrated water is absorbed in the small intestine as soon as it leaves the stomach. Alcohol does not absorb into the stomach. Alcohol is also absorbed in the small intestine as soon as it leaves the stomach.

Answer 3

It depends on the nutrient. Some things pass directly through the stomach wall (alcohol is veeeeerrry guilty of this), but most enter the body through the small intestine. Different nutrients will enter the bloodstream at different points. Water is pulled out at several different points, most notibly the large intestine.

Answer 4

Intestines. The stomach is basically a pouch used to churn food and begin the digestive breakdown - it has limited surface area and therefor limited nutritional absorption.

The small intestines are long and thin with lots of surface area and is very effective at allowing broken down food to pass near blood vessels transferring nutrients.

The large intestines are relatively short and mostly draw out moisture prior to passing.

Answer 5

nutrients are absorbed at both the kidneys and intestines... the bulk of your food is absorbed into the body at the duodenum, which is the part of the small intestine right after the stomach...

water is absorbed at the large intestine and goes to blood immediately...

however, water that is absorbed is still not processed,
it goes to the kindeys through an array of blood 'pathways'

it goes into the kidneys and blood passes through these tiny things called NEPHRONS which take out plasma ions, sodium, pottasium and many nutrients and pass them into the blood again... this is the total process of absorption of nutrients into blood......

Answer 6

In the stomach, your food is reduced to chyme, a thick creamy subtance which is then pushed into your small intestines where most of your nutrients are digested. It also depends on whether it is protein, fat or phosphates. Certain enzymes digest certain things depending on where the enzyme is. An example would be protein. Protein is digested by pepsin . Pepsin is found in the stomach and can only be activated by a high pH in the stomach. It all depends on the enzyme and where it is found and how it works. Pepsin works on protein because your stomach needs a high acidic content to break down food. You just need to do some research.

Answer 7

The large intestine.

Answer 8

the small intestine after the duodenum, this is done by microvilli

m b: you are wrong, the duodenum is where chyme is broken down by pancreatic enzymes and bile.

NOTHING IS ABSORBED IN THE STOMACH, even alcohol, actually maybe a little alcohol can get absorbed in the stomach, where do you people get your information, jeez!

Answer 9

the duodenum of the small intestine

Answer 10
