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: -Jejunum: The middle section of the small intestine carries food through rapidly, with wave-like muscle contractions, towards the ileum. 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: -Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream.

Detailed explanation-4: -Nutrients inside the villi (small intestine) move into the blood through osmosis because the nutrient is in more abundance in the villi than the blood stream.
