It removes all the unnecessary things absorbed from the intestine and ensures that fully processed and safe nutrients enter the bloodstream. Food does not stay there, and its only role is the transfer of food from the mouth to the stomach. Enzymes are chiefly responsible for carrying out chemical digestion and are secreted in the central cavity of the alimentary canal., The digestive system is also known as the alimentary canal from the mouth to the anus., * The wall of the stomach is elastic ( large meals can be swallowed quickly, stored and then gradually released in the small intestine), The digestive process involves the mixing of food, the movement of food through the digestive tract, and a chemical breakdown of large molecules of food into smaller molecules.
