본문내용

■ macrostructure
· the largest gland, about 2.5% of body weight
· the rib cage encloses the liver except for the lower margin (Figure 63-1)
· two lobes (falciform ligament로 나뉘어짐)

■ microstructure
· the functional unit of the liver : lobule (cylindrically shaped, 1.5mm in diameter, 8mm in length)
· each lobe :50,000 - 100,000 lobules, microanatomy of lobules (Figure 30-5)

■ Circulation(Figure 63-3)
· portal vein(1000ml/min), hepatic a.(350ml/min), 1/4 of CO
· 500ml up to 1000ml - blood supply in emergency situation.
( blockage within the portal venous sys. -> LC 가능, portal hypertension)
· hepatic artery : oxygenated blood
· portal vein : deoxygenated blood
(pancreas, spleen, stomach, intestine, GB -> superior/inferior mesentric vein, splenic vein -> portal vein )
; disgestive organs -> nutrients, metabolites, toxins -> detoxifecation, assimilation, processing (c.f., antechamber of the heart)
