Study Notes
Digestive System Overview
- The salivary glands produce digestive enzymes such as amylase and lingual lipase.
Phases of Digestion
- The cephalic phase of digestion primarily takes place in the mouth, involving the mechanical breakdown of food by chewing, and formation of the bolus, which is primarily composed of food, saliva, and air.
Gastric Phase
- The gastric phase of digestion primarily occurs in the stomach, where gastric acid breaks down food into a liquid mixture called chyme, and its primary function is to denature proteins.
- Gastric acid is essential in the gastric phase of digestion.
Intestinal Phase
- The pancreas is an accessory organ responsible for producing enzymes involved in the intestinal phase of digestion.
- The small intestine is where the intestinal phase of digestion takes place, involving the breakdown of nutrients.
Accessory Organs
- The gallbladder's primary function in the digestive system is to store bile produced by the liver.
