Study Notes
Accessory Glandular Organs
- The organs considered accessory glandular organs in the digestive system are the salivary glands, pancreas, and liver.
Digestion Process
- Chyme is a semi-fluid mixture of food and digestive enzymes that forms in the stomach.
- Digestion primarily begins in the mouth, where food is broken down into smaller particles by mechanical and enzymatic action.
- The function of the gastrointestinal tract (GI tract) is to break down ingested food into absorbable nutrients.
Microorganisms in Digestive System
- Commensal microorganisms in the digestive system help with digestion, produce vitamins, and regulate the immune system.
Nutrient Absorption
- The small intestine is responsible for the absorption of nutrients into the bloodstream.
GI Tract Wall Structure
- The submucosal layer of the GI tract wall contains the submucosal plexus of the enteric nervous system.
Stomach Function
- The pyloric valve in the stomach regulates the flow of food into the small intestine.
Surface Area Increase
- The structures that increase the surface area of the GI tract are villi and microvilli in the small intestine.
Waste Elimination
- The rectum is the last part of the digestive system before elimination of waste.
