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: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins. The lowest part of your small intestine is the ileum. This is where the final parts of digestive absorption take place.

Detailed explanation-3: -The small intestine is the main site of nutrient absorption, the Springfield Technical Community College Anatomy and Physiology website notes, but some nutrients are absorbed in the large intestine.

Detailed explanation-4: -The large intestine (or colon, or large bowel) is the last structure to process food, taking the undigestible matter from the small intestine, absorbing water from it and leaving the waste product called feces. Feces are expelled from the body through the rectum and the anus.
