Describe the anatomical position of the liver
• Occupies most of the R. hypochondriac and epigastric regions
State the seven functions for the liver
• Bile production • Phagocytosis of red blood cells and bacteria • Processing nutrients (carbohydrates, fats, proteins) • Storage (Fe2+, glycogen, vitamins) • Formation of blood components (plasma proteins, clotting factors) • Detoxification of alcohol, drugs, converts toxic ammonia to urea Heat production
Name the two blood vessels that supply the liver & the vein that exits the liver
Hepatic artery - branches from the aorta providing oxygenated blood Hepatic portal vein - brings nutrient - rich blood into the liver from the stomach, spleen and intestines The hepatic veins take deoxygenated blood to the inferior vena cava
State the function of the stellate reticuloendothelial (Kupffer’s) cells
Remove debris, like bacteria and worn out blood cells, from the blood as it flows past
Name the cells that produce bile
Hepatocytes (produce 500 - 1000mLs of bile/day)
Name the structure that stores bile
Gallbladder
Describe the main function of bile
Neutralise acid from the stomach, emulsification of fat to enable digestion and absorption of lipids and remove waste
Describe the anatomical position of the pancreas
Located posterior to the stomach in the epigastric region
