—The esophagus is a muscular tube that connects the pharynx to the stomach
—Disease: Gastroesophageal reflux disease (GERD)

— medical test: Endoscopy
—Coordinated peristalsis of the esophageal walls keeps food moving
2. Stomach
—Four main regions: cardia, fundus, body, and pylorus
*Contains rugae (thick folds) that expand
*Two sphincters control food movement:
-lower esophageal
- pyloric
*Processes food into chyme
—disease: Peptic Ulcer Disease (stomach ulcer)
—medication: Antacids, Antidiarrhoeal
—medical test: CAT scan
3. Small Intestine
—Consists of :
*duodenum (10 inches),
*jejunum (8 feet)
*ileum (12 feet)
