The food passes to the stomach where it is churned and mixed with acidic gastric juice that begins the digestion of protein. The pancreas produces pancreatic juice that contains many of the enzymes secreted into the small intestine. In addition to producing bile the liver regulates blood sugar levels by converting glucose absorbed by the villi into glycogen and storing it.

Villi increase the surface area of the small intestine and allow nutrients, such as protein, carbohydrates, fat, vitamins, and minerals, to absorb through the intestinal wall and into the bloodstream.

The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation.

Arrange the following parts of the digestive system in the order in which food passes through on the way from the mouth to the anus. The digestive enzymes in the gut break down the large food molecules into smaller ones that can be absorbed through the walls of the villi.

Melena is typically caused by bleeding in the upper part of the gastrointestinal tract, such as the esophagus, stomach, or the first part of the small intestine, or due to the patient swallowing blood.

The physical defenses of innate immunity include physical barriers, mechanical actions that remove microbes and debris, and the microbiome, which competes with and inhibits the growth of pathogens. The skin, mucous membranes, and endothelia throughout the body serve as physical barriers.
