Digestive System Functions
- The digestive system breaks down food into smaller particles that the body can absorb.
- The system is responsible for transporting food through the body and absorbing nutrients.
Main Organs and Their Functions
- Esophagus: Connects the mouth to the stomach and moves food down via peristalsis.
- Stomach: Breaks down food both chemically and physically.
- Small Intestine: Absorbs sugars, fats, and proteins into the bloodstream. The villi increase the surface area for absorption.
- Large Intestine: Absorbs water and releases solid waste.
Digestion vs Absorption
- Digestion: The breakdown of food into smaller particles/nutrients.
- Absorption: The intake of digested food into the bloodstream.
Maintaining a Healthy Digestive System
