The role of small intestine in
Digestion
The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.
Absorption
The small intestine is the part of the intestines where 90% of the digestion and absorption of food occurs, the other 10% taking place in the stomach and large intestine. The main function of the small intestine is absorption of nutrients and minerals from food.
Assimilation
Assimilation is the process of absorbing nutrients during digestion and distributing them to the body for growth and repair. The small intestine uses microvilli to absorb nutrients. ... The blood then carries water to the rest of the body.
