Study Notes
Digestive System Anatomy Overview
- The oesophagus is located posterior to the trachea and enters the peritoneal cavity through the diaphragm.
- The stomach occupies specific abdominal regions and functions in food storage, mechanical breakdown, and chemical digestion.
- The small intestine is the primary site for nutrient digestion and absorption, with the majority of absorption occurring there.
- The duodenum has specific parts and papillae, while the jejunum and ileum differ in structure and function.
- The large intestine consists of the cecum, ascending, transverse, descending, and sigmoid colon.
- The rectum serves as a temporary storage for fecal material and triggers the urge to defecate.
- The salivary glands include the parotid, submandibular, and sublingual glands, each with specific ducts.
- The liver produces bile, metabolizes nutrients, and detoxifies the blood, with a complex system of veins and ducts.
- The pancreas functions as both an exocrine and endocrine gland, producing digestive enzymes and insulin/glucagon.
- The arterial system includes the celiac trunk, superior mesenteric artery, and inferior mesenteric artery, each with specific vascularization targets.
- The venous system includes renal veins, gonadal veins, and common iliac veins, as well as the portal vein formed by the splenic, superior mesenteric, and inferior mesenteric veins.
- The text references multiple anatomy resources, including "Gray's Basic Anatomy" and "Atlas of Human Anatomy."
