NEET PG DENTAL EXAM

Detailed explanation-1: -Absorption. 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: -Passing into the blood The small molecules of nutrients produced during digestion pass into the bloodstream through the wall of the small intestine. They are then transported around the body. The small intestine needs to absorb the nutrients quickly, before the undigested food passes out of the body.

Detailed explanation-3: -Enterocytes are the major cell type in intestinal epithelium. They are simple columnar epithelial cells and play important roles in nutrient absorption (e.g., ions, water, sugar, peptides, and lipids) and in secreting immunoglobulins.

Detailed explanation-4: -Digestion occurs when food is moved through the digestive system. It begins in the mouth and ends in the small intestine. The final products of digestion are absorbed from the digestive tract, primarily in the small intestine.
