Vitamin absorbtion

Vitamins are very important helpers for human being survival . Vitamins are absorbed in small intestines. The two types of vitamins : first water-soluble vitamins (all the B vitamins and vitamin C) and second fat-soluble vitamins (vitamins A, D, E, and K).
Fat-soluble vitamins are stored in the liver and fatty tissue of the body. Water-soluble vitamins are not easily stored and excess amounts go away from body in urine.

Protein digestion

Protein is very critical biological components of life. I mean we are all of us need proteins to maintain our daily body systems. Foods such as meat, eggs, milk, cheese, beans contains lots of molecules of protein. we will use proteins to repair our body. An enzyme in the juice of the stomach starts the digestion of swallowed protein. Then in the small intestine, several enzymes from the pancreatic juice and the lining of the intestine complete the breakdown of huge protein molecules into small molecules called amino acids. These small molecules can be absorbed through the small intestine into the blood and then be carried to all parts of the body.

Why is digestion important?

So you can ask why is digestion is very important. Let me explaing : when you eat some foods—such as bread, meat, fruits, pizza etc. The body cant use them as in this form. It must be suitable for body cells. Food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. So this mean that we need digestion process. Digestion is the process by which food and drink are broken down into their smallest parts so the body can use them to build and nourish cells and to provide energy.
