How the Digestive System Works | 3D Animation
1. Mouth:
- Mechanical Breakdown: Teeth break down food into smaller pieces through chewing.
- Chemical Breakdown: Saliva, containing enzymes like amylase, begins breaking down carbohydrates.
2. Esophagus:
- Peristalsis: Muscular contractions propel food down the esophagus to the stomach.
3. Stomach:
- Mechanical Breakdown: Churns and mixes food with gastric juices.
- Chemical Breakdown: Gastric acid and enzymes break down proteins.
4. Small Intestine:
- Chemical Breakdown: Receives digestive juices from the pancreas (enzymes for breaking down carbohydrates, proteins, and fats) and liver (bile for fat digestion).
- Absorption: Nutrients are absorbed into the bloodstream through the intestinal walls.
5. Large Intestine (Colon):
- Water Absorption: Absorbs water and electrolytes from undigested food.
- Waste Storage: Stores waste products until they are eliminated.
6. Rectum and Anus:
- Waste Elimination: Stores stool until it is expelled from the body through the anus.
Key Organs and Their Roles:
- Liver: Produces bile to aid in fat digestion.
- Pancreas: Produces digestive enzymes and hormones like insulin.
- Gallbladder: Stores and releases bile into the small intestine.
Overall, the digestive system is a remarkable process that involves a series of mechanical and chemical actions to break down food, absorb nutrients, and eliminate waste.
