Study Notes
Digestive System Lecture Notes
- The lecture covers the anatomy and physiology of the digestive system, including the small and large intestines, the pancreas, and the liver
- The small intestine is crucial for nutrient absorption, comprising the duodenum, jejunum, and ileum
- The duodenum receives chyme from the stomach and digestive secretions from the pancreas and liver, plays a role in neutralizing stomach acid, and contains Brunner's glands
- The jejunum and ileum are vital for nutrient absorption through diffusion and active transport
- The small intestine's lining features circular folds (plicae circulares), intestinal villi, and microvilli to increase surface area for maximum absorption
- The pancreas is an exocrine gland producing enzymes (e.g., amylase, lipase, nucleases, proteases) and endocrine tissue producing hormones (e.g., insulin, glucagon)
- Pancreatic juice secretions are approximately 1000mL per day, controlled by hormones from the duodenum.
- The liver's anatomy includes lobes, a fibrous capsule, and a visceral peritoneum covering
- Its significant functions include metabolic regulation (blood composition adjustments, nutrient metabolism, waste removal, nutrient storage, and drug inactivation), haematological regulation (blood reservoir, phagocytosis, protein synthesis, and toxin removal), and bile production
- Bile's role is to emulsify fats, increasing their surface area for enzyme digestion, crucial for lipid absorption
- The gallbladder stores and concentrates bile, releasing it into the small intestine in response to cholecystokinin (CCK) from the duodenum
- The large intestine, also known as the large bowel, is horseshoe-shaped and extends from the ileum to the anus
- It primarily absorbs water, compacts intestinal contents into feces, absorbs vitamins produced by bacteria, and stores feces until defecation
- The large intestine comprises the cecum (with appendix), colon (ascending, transverse, descending, and sigmoid), and rectum, followed by the anal canal
- The anal canal features internal and external sphincters, controlling defecation.
- The composition of digestive enzymes and how they operate is further detailed to aid understanding.
- Clinical information about colorectal cancer was included in the lecture, including its prevalence, screening initiatives (in the UK), and risk factors.
