Detailed explanation-1: -As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
Detailed explanation-2: -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-3: -General features of digestion and absorption. There are four means by which digestive products are absorbed: active transport, passive diffusion, facilitated diffusion, and endocytosis.
