Study Notes

Digestive System Overview

The digestive system's primary function is to break down ingested food into smaller molecules that can be absorbed and utilized by the body for energy, growth, and repair.

Mechanical Processes

Mastication: the process of chewing food in the mouth, which breaks down food into smaller pieces, increasing the surface area for enzymatic digestion.
Propulsion: the movement of food through the digestive system, facilitated by muscle contractions and relaxations.
Mixing: the combination of food with digestive enzymes and acids to facilitate chemical digestion.

Elimination

Defecation: the process of eliminating waste products from the body through the anus.

Note: These notes focus on the key concepts related to the functions and processes of the digestive system.
