DIGESTION

DIGESTION 

Digestion is the process by which the body breaks down food into nutrients that can be absorbed and utilized for energy, growth, and repair. 

Here's a step-by-step explanation of the digestion process:

1. MOUTH: Food is chewed and mixed with saliva that contains enzymes to break down carbohydrates.

2. ESOPHAGUS: Food is swallowed and passes through the esophagus into the stomach.

3. STOMACH: The stomach secretes digestive enzymes and acids to break down proteins and fats.

4. SMALL INTESTINE: Nutrients are absorbed into the bloodstream through the walls of the small intestine.

5. PANCREAS: The pancreas secretes digestive enzymes to break down carbohydrates, proteins, and fats.

6. LIVER: The liver produces bile to aid in fat digestion and absorption.

7. LARGE INTESTINE: Water and electrolytes are absorbed, and the remaining waste is prepared for elimination.
