Which action is the main function of the digestive system?
Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals. These complex macromolecules must be broken down and absorbed in the gastrointestinal (GI) tract.

What are the five functions of the gastrointestinal system?
Chapter Review. The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.

What are the three phases of gastric activity?
The process of gastric secretion can be divided into three phases (cephalic, gastric, and intestinal) that depend upon the primary mechanisms that cause the gastric mucosa to secrete gastric juice.
What are the phases of gastric activity?
Gastric secretion occurs in three phases: cephalic, gastric, and intestinal. During each phase, the secretion of gastric juice can be stimulated or inhibited.
What is the gastric phase?
The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity. About two-thirds of gastric secretion occurs during this phase. Ingested food stimulates gastric activity in two ways: by stretching the stomach and by raising the pH of its contents.
What are the three components of gastric juice?
Gastric juice is made up of water, electrolytes, hydrochloric acid, enzymes, mucus, and intrinsic factor. Hydrochloric acid is a strong acid secreted by the parietal cells, and it lowers your stomach’s pH to around 2.
