Study Notes
Digestion Process
- Begins in the mouth, where food is broken down into smaller pieces
- Involves mechanical and chemical breakdown of food
Esophagus
- Responsible for transporting food to the stomach
Enzymes
- Lipase breaks down lipids (fats) in the small intestine
- Amylase breaks down carbohydrates in the mouth
- Trypsin breaks down proteins in the small intestine
- Pepsin breaks down proteins in the stomach
Stomach
- Primary function is mechanical breakdown of food
- Produces hydrochloric acid and enzymes to aid in digestion
- Responsible for chemical digestion of proteins
Liver and Gallbladder
- Liver produces bile, which is stored in the gallbladder
- Bile helps to emulsify fats in the small intestine
- Liver's main function is to detoxify harmful substances
Small Intestine
- Jejunum is responsible for the majority of nutrient absorption
- Villi increase the surface area for absorption of nutrients
Pancreas
- Main function is to produce insulin
- Also produces digestive enzymes to aid in digestion
Large Intestine
- Role is to store feces
- Also absorbs water and electrolytes
Other Components
- Epiglottis prevents food from entering the trachea during swallowing
- Sphincter muscles control the passage of food through the digestive system
- Appendix is a reservoir for beneficial bacteria
