Study Notes
Alimentary Canal
- The alimentary canal, also known as the gastrointestinal (GI) tract, includes the mouth, esophagus, stomach, small intestine, and large intestine.
Digestion of Large Food Molecules
- The purpose of digestion of large food molecules is to break them down into smaller, absorbable nutrients that can be utilized by the body for energy, growth, and repair.
Peristalsis
- Peristalsis is a muscular contraction that helps to mix food with digestive enzymes and move it through the digestive system, ensuring that nutrients are absorbed efficiently.
Villi in the Small Intestine
- The villi in the small intestine are finger-like projections that increase the surface area for absorption, allowing for more efficient uptake of nutrients into the bloodstream.
Food Processing
- The purpose of food processing in the digestive system is to break down complex food molecules into simpler, absorbable forms, making it possible for the body to extract nutrients and energy.
Components of the Human Digestive System
- The human digestive system consists of the mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, and gallbladder.
- The spleen is NOT a component of the human digestive system.
Roles of Peristalsis and Villi
- The main function of peristalsis is to facilitate the mixing of food with digestive enzymes and the movement of food through the digestive system.
- The main function of the villi in the small intestine is to increase the surface area for absorption, allowing for more efficient uptake of nutrients into the bloodstream.
Importance of Digestion
- Digestion of large food molecules is essential in the digestive system because it allows for the breakdown of complex nutrients into simpler forms that can be absorbed and utilized by the body.
