Study Notes
Digestive System Overview
- The mouth is the entry point for food and the place where digestion begins.
- Saliva, a fluid containing digestive enzymes, assists in the digestive process.
- The dental formula is a representation of tooth types in humans.
- Deciduous teeth are temporary teeth that are lost during childhood.
- Permanent teeth are adult teeth that replace deciduous teeth.
- The pharynx is a muscular tube connecting the mouth to the esophagus.
- The esophagus is the tube that transports food to the stomach.
- Swallowing is the mechanism of moving food from the mouth to the stomach.
- The stomach is a muscular organ that stores food and aids in its digestion.
- Gastric juice, containing hydrochloric acid and enzymes, is a digestive fluid found in the stomach.
- Gastric secretions are controlled by neural and hormonal mechanisms.
- Enteroendocrine G cells produce gastrin in order to stimulate gastric secretions.
- Histamine is a chemical which stimulates the release of HCl from parietal cells.
- Ghrelin is a hormone, released before meals, that stimulates hunger.
- Semaglutide is a drug used to reduce appetite and treat type 2 diabetes.
- Cephalic, gastric, and intestinal are the three gastric phases.
- Hydrochloric acid is an acidic component that facilitates digestion in the stomach.
- Peristalsis refers to wave-like muscle contractions moving food through the GI tract.
- Hepatocytes are liver cells responsible for processing of nutrients and detoxification.
- Liver lobules are the functional units of the liver, each with central veins.
- The portal triad contains the hepatic artery, portal vein, and bile duct.
- The liver can regenerate itself after damage.
- Hepatitis refers to inflammation of the liver, often caused by a virus.
- Cirrhosis is the scarring of the liver as a result of chronic damage.
- Non-alcoholic fatty liver disease is the accumulation of fat in the liver, affecting 25% of the population.
- The gallbladder stores and concentrates bile for digestion.
- The pancreas secretes digestive enzymes and bicarbonate into the intestine.
- The bile duct carries bile from the liver to the duodenum.
- Alkaline tide is an increase in blood pH following HCl secretion.

Description
Explore the initial stages of digestion, starting from the mouth where food enters and mixes with saliva. Learn about teeth, the pharynx, and the esophagus transporting food to the stomach, where gastric juices break it down further. Understand the roles of gastrin and histamine.
