Digestive System

The digestive system breaks down food into nutrients for absorption and eliminates waste. It includes the alimentary canal (GI tract) from mouth to anus, plus accessory organs like the liver, pancreas, and gallbladder.

Key Structures

Oral cavity, teeth, and tongue

Esophagus

Stomach (regions and sphincters)

Small intestine (duodenum, jejunum, ileum)

Large intestine (cecum, colon, rectum, anal canal)

Liver and biliary system

Pancreas

Mesenteries and peritoneum

Study Tips

✓Learn the GI tract as a continuous tube with regional specializations
✓Study blood supply with celiac, SMA, and IMA distributions
✓Understand peritoneal relationships (intraperitoneal vs retroperitoneal)
✓Focus on sphincters and their clinical significance

Clinical Relevance

GI anatomy is crucial for understanding abdominal pain, performing endoscopy, and surgical interventions. Knowledge of blood supply helps predict ischemic patterns and surgical planning.

Digestive System FAQs

Common questions about the digestive system

The small intestine consists of the duodenum (C-shaped, around pancreatic head), jejunum (upper 2/5, more vascular), and ileum (lower 3/5, contains Peyer's patches).

The parietal peritoneum lines the abdominal wall and is pain-sensitive. The visceral peritoneum covers organs and is sensitive only to stretch and ischemia.
