NEET BIOLOGY

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: -The small intestine is a major site for chemical digestion and absorption of key food components, such as amino acids, peptides, and glucose for energy.

Detailed explanation-3: -Digestion of food involves both physical and chemical processes. Through digestion, large food particles are converted into smaller components that can be readily absorbed into the bloodstream.

Detailed explanation-4: -During chemical digestion, your food is broken down into very small pieces that your cells can absorb. Your cells will use the nutrients available from chemical digestion to make energy and new cells. This process is called metabolism.

Detailed explanation-5: -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.
