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.
