Study Notes
Digestive System Overview
- The digestive system consists of proteins, carbohydrates, and fat (triacylglycerol) as major components.
- It comprises organs such as the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and accessory organs like salivary glands, liver, pancreas, and gallbladder.
- The mouth mechanically breaks down food with teeth and tongue, while saliva, produced by the salivary glands, moistens and begins to break down carbohydrates.
- The stomach acts as a temporary storage container for food and carries out mechanical and chemical digestion through muscle contractions and gastric juice, creating a semiliquid form called chyme.
- The small intestine is the main site for chemical digestion and nutrient absorption, featuring anatomical features like large circular folds, villi, and microvilli for increased nutrient absorption.
- The small intestine secretes enzymes like peptidases, sucrase, lactase, maltase, pancreatic amylase, trypsin, chymotrypsin, and pancreatic lipase, aiding in digestion.
- The large intestine is responsible for the absorption of water, electrolytes, vitamins, and minerals, and serves as an ecosystem for trillions of microorganisms.
- Digestive hormones like gastrin, ghrelin, and secretin are produced by different parts of the digestive system and have specific functions in stimulating appetite, inhibiting hunger, and regulating gastric secretions and motility.
- The digestive system plays a crucial role in breaking down food into nutrients and energy for the body.
- The organs of the gastrointestinal tract, along with accessory organs, work together to ensure the digestion and absorption of essential nutrients.
- The small intestine is the primary site for nutrient absorption and features various secretions that aid in the digestion process.
- The large intestine is responsible for the absorption of water, electrolytes, vitamins, and minerals, and serves as an ecosystem for microorganisms.
