Why is the small intestine important?

Answer 1

Most of the digested molecules of food, as well as water and minerals, are absorbed through the small intestine. The mucosa of the small intestine contains many small folds that are covered with tiny fingerlike projections called villi. The villi are covered with microscopic projections called microvilli. These structures create a vast surface area through which nutrients can be absorbed. Specialized cells allow absorbed materials to cross the mucosa into the blood, where they are carried off in the bloodstream to other parts of the body for storage or further chemical changes.

Answer 2

the small intestine is small of course and The food that you eat goes to your stomach and it turns into a liquid then it flows to your small intestine. The villi help to absorb the nutrients from the liquified food. Basically, the small intestine helps absorb nutrients from your food.

Answer 3

Well, the small intestine actually does a lot of the digesting. Inside of the small intestine are small, finger-like villi that absorbs nutrients. Without it, your digestive system can not function correctly.

Answer 4

The small intestine is about 6 meters (20 feet) long. It is coiled in the center of the abdominal cavity. The small intestine is divided into 3 sections: upper, jejunum, and ileum. The lining of the small intestine secretes a hormone called secretin, which stimulates the pancreas to produce digestive enzymes. The basic function is to aid in the absorption of nutrients and certain toxins, the latter of which are absorbed and filtered by the liver and indirectly through the kidneys.

Answer 5

Because although most of the nutrients you ingest begin to be digested in the mouth and stomach, it is the digestive enzymes from the pancreas and bile from the liver/gallbladder that finish digesting your food in the duodenum of the small intestine.

Answer 6

You cannot say this. It is one of the most important ones because it allows us to digest and absorb food, without which we die. However, it will do you no good without functioning heart, lungs, liver, kidneys, and brain, to name only a few of what are accurately called vital organs.

Answer 7

Because the small intestine does most of the digesting.
