The digestive tract basically breaks down the macromolecules into monomers to be absorbed into the body. Various enzymes are involved in the process of digestion. Digestive tract in humans starts from the mouth and ends at anus.
The beginning of the opening of the second part of the digestive tract
Mammals have a complete digestive tract, it starts from mouth to anus. Although each species have some different type and length of tract, they have esophagus, ventriculus, intestinum which function to support a complete food metabolism. Besides, some digestive glands also support this function.
Several systems do this function, the kidneys, the respiratory tract, the lower digestive tract and the skin.

Absorptive surfaces are more likely to be found in organs like the small intestine, where nutrients are taken up into the bloodstream. Secretory surfaces are more common in organs like the salivary glands or pancreas, where substances are released into the body or digestive tract.
The complete lining of a person's digestive tract is renewed approximately every 3-5 days. This rapid turnover is necessary to replace old cells and maintain the health and function of the digestive system.

responsible for the continual movement of food along the digestive tract
The large intestine is in charge of absorbing water.
The digestive tract lining is primarily composed of epithelial cells that serve protective and absorptive functions. Mucus-secreting goblet cells within the lining help lubricate and protect the gut from mechanical and chemical damage. Additionally, various hormones and signaling molecules regulate the function and health of the lining, influencing digestion, absorption, and immune responses. Overall, a balance of these components is essential for maintaining a healthy digestive system.
The anus is the last part of the digestive tract.
