Study Notes
Digestive System Anatomy Overview
- The esophagus is located behind the trachea and enters the peritoneal cavity through the diaphragm.
- The stomach occupies multiple abdominal regions and plays a role in food storage, mechanical breakdown, and chemical digestion.
- The small intestine is responsible for the digestion and absorption of nutrients, with the duodenum having specific parts and papillae.
- The large intestine consists of different sections, including the cecum, ascending colon, transverse colon, descending colon, and sigmoid colon.
- The rectum serves as a temporary storage for fecal material and triggers the urge to defecate.
- The accessory organs include salivary glands, liver (produces bile, metabolizes nutrients, and detoxifies blood), and pancreas (exocrine and endocrine functions).
- The arterial system comprises the celiac trunk, superior mesenteric artery, and inferior mesenteric artery for vascularization.
- The venous system includes renal veins, gonadal veins, and common iliac veins, along with the portal vein formed by the splenic, superior mesenteric, and inferior mesenteric veins.
