Study Notes
Chemical Digestion
- Breaks down food into molecules using enzymes or acids.
- Essential for nutrient absorption in the digestive system.
Stomach Functions
- Performs chemical digestion by utilizing enzymes and acids to break down food.
- Does not primarily carry out mechanical digestion, which is mainly the role of teeth and muscles.
Enzyme Production
- Key organs involved in producing enzymes or digestive juices include:
- Stomach
- Small intestine
- Pancreas
Alimentary Canal Sequence
- Food passes through the following organs in this order:
- Mouth
- Esophagus
- Small intestine
- Large intestine
Villi
- Microscopic, finger-like structures located in the small intestine.
- Increase internal surface area, enhancing nutrient absorption from digested food.
Large Intestine Nutrient Absorption
- Absorbs primarily water and minerals.
- Plays a crucial role in maintaining body hydration and electrolyte balance.
