ANATOMY

Detailed explanation-1: -The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.

Detailed explanation-2: -Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Detailed explanation-3: -The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

Detailed explanation-4: -The food that is digested is absorbed into the blood vessels in the walls of the intestine. The finger-like projections known as villi, drastically increase the surface area of the small intestine for greater absorption of the digested food. The blood carries the absorbed food material to different parts of the body.

Detailed explanation-5: -The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body.
