What is Poal Acinus in liver is centerd on? and explain in detail?
Poal Lobules - The vessels in a poal triad usually give branches to pas of three adjoining lobules. The area of liver tissue (comprising pas of three hepatic lobules) supplied by one branch of the poal vein is regarded by many authorities as the true functional unit of liver tissue, and is referred to as a poal lobule. A still smaller unit, the poal acinus has also been described. It consists of a diamond shaped area of liver tissue supplied by one hepatic aeriole running along the line of junction of two hepatic lobules. Two central veins lie at the ends of the acinus.
