ANATOMY

Detailed explanation-1: -The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.

Detailed explanation-2: -The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change.

Detailed explanation-3: -The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.

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: -The small intestine has a vast interior surface area, which makes it good for absorption. This is created by the plicae circulares, which project numerous microscopic tissue structures that resemble fingers and are known as villi.
