Liver:
- diaphragmatic (anterior) and visceral (posterior) surfaces
- right, left, quadrate and caudate lobes
- peritoneum:
- falciform ligament: round ligament
- coronary ligament: bare area
- lesser omentum
-
lecture notes
- largest lobe is the right lobe
- quadrate is anterior, caudate is posterior
- coronary ligament- connects liver to diaphragm
- round ligament/ligamentum teres,- the obliterated umbilacral cord
-
porta hepatis (hilus):
- portal (hepatic) triad:
- hepatic artery (proper): branch of celiac artery----carries oxygenated blood to the liver tissues
- (hepatic) portal vein: carries nutrient‑rich venous blood from the digestive tract
- bile duct: carries bile from the liver
-
lecture notes
- porta hepatis- where major things enter or leave liver
- 2/3 of the blood going to the liver is from the portal vein
- hepatic veins empty into the inferior vena cava (can be embedded in the liver)
- gall bladder attatched anteriorly
-
-
lecture notes
- is divided into lobules
- triads are found at the perferee of the lobules (artery, veins and duct)
- hepadocytes (liver cells) are arranged in chords and at the center is a vein and on the out side are the triads
- arteries and veins give blood to the sinusoids (leaky capillaries) which leak into the peri sinusoidal space which is then absorbed by the hepatic cells
- in the wall of capillaries there a cooper cells which remove debris
