The liver is located in the epigastric region and right hypochondriac region (above the transpyloric plane and on the right side of the right midinguinal line). It lies under the diapraghm, connected by ligamentum coronaria and some of the liver is protected by the ribs. (MedScape, 2013) According to health line, liver has many functions: 1. Producing bile 2. Detox toxins from the blood 3. Stores vitamins, iron, and glucose 4. Able to convert stored glucose to usable glucose 5. Destruct hemoglobin 6. Destroys old erythrocytes 7. And converts ammonia to urea (Health Line, 2013) The liver is capsulated by Glisson’s Capsule, which is invaginates at liver hilum, becomes continuous with intrahepatic portal connective tissue & encases braches of portal vein, hepatic artery and bile duct, and lymphatic channels (a.k.a portal triads). (Cleveland State University, 2008) For the vascularization, the liver has blood supply from vena portae hepatis (poor in oxygen) and the arteria hepatica propria (rich in oxygen). The blood from vena portae hepatis is rich in nutrient but poor in oxygen, but arteria hepatica propria is rich in oxygen but poor in nutrient. The blood that comes from vena portae hepatis and arteria hepatica propria will enter the sinusoids of the liver to detox its toxin (vena portae hepatis) and supply the liver with the oxygen (arteria hepatica propria), and then the blood continue its flow to the heart by draining to vena centralis of the vena hepatica. From the vena centralis, the blood goes to the vena cava inferior to return to the heart. Vena portae hepatis is majorly formed by vena mesenterica superior, that collects blood from pancreas, small intestines, and colon, and the vena splenica, that collects blood from the... ... middle of paper ... ... (supplies blood the left side of gaster), and arteria hepatica communis (supplies blood to the liver). (MedScape, 2013) After that, the arteria hepatica communis gives arise to arteria gastroduodenalis (this artery gives arise to arteria supraduodenalis and arteria pancreatic duodenalis posterior superior) and continues as the arteria hepatica propria that goes to the liver to supply the oxygenated blood.
