HUMAN NUTRITION

Detailed explanation-1: -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-2: -The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

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 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. The ileum absorbs bile acids, fluid, and vitamin B-12.

Detailed explanation-5: -Most of the nutrient transport occurs in the small intestine, whereas the colon is primarily responsible for water and electrolyte transport.
