Study Notes
The Digestive System
- The digestive system breaks down food into micronutrients for energy and building blocks.
- Indigestible parts are eliminated.
- The alimentary canal, or digestive tract, is a hollow, muscular tube from mouth to anus.
- It has different layers with specialized functions.
Components of the Digestive System
- Alimentary canal:
- Mouth: food entry point.
- Pharynx: back of the throat.
- Esophagus: connects pharynx to stomach.
- Stomach: mixes and breaks down food.
- Small intestines: primary nutrient absorption site.
- Large intestines: absorbs vitamins and water.
- Anus: waste excretion.
- Accessory structures:
- Oral cavity (tongue, teeth, salivary glands).
- Pancreas: releases digestive enzymes.
- Liver: produces bile for fat digestion.
- Gallbladder: stores and concentrates bile.
Functions of the Digestive System
- Ingestion: Taking in food.
- Secretion: Release of enzymes and mucus.
- Enzymes break down proteins, fats, and carbohydrates.
- Mucus protects the digestive tract lining.
- Mixing and Propulsion: Mixing food and movement through the tract via peristalsis.
- Digestion: Food breakdown.
- Mechanical digestion: physical breakdown by teeth and tongue.
- Chemical digestion: enzymatic breakdown of food molecules.
- Absorption: Nutrient uptake.
- Bloodstream: primary absorption route.
- Lymphatic system: absorbs fats.
- Excretion: Waste removal.
- Defecation: waste elimination through the anus.
