How the Body Works : The Architecture of the Liver

The Architecture of the Liver

The liver is the largest organ in the body. Liver tissue is composed of a compact mass of multisided units, known as the hepatic lobules. Each lobule consists of a central vein, which acts as a tributary of the hepatic vein and conducts processed blood away from the lobule, surrounded by plates of liver cells. The liver receives blood from two sources, 80 percent, which carries digested food materials, arrives from the intestine via the portal vein and venules; the remaining twenty percent is oxygenated blood from the heart, which enters through the hepatic artery and arterioles. An exchange of materials takes place between the liver cells and the blood, which then passes into the central veins and returns to the general body circulation via the hepatic vein. Sinusoids, spaces between plates of liver cells composed of tributaries of the hepatic artery and portal vein, conduct the blood flow to the central vein. The bile canaliculus carries bile juice from the liver to branches of the bile duct which convey bile from the lobules to the gall bladder. When an adult is at rest, about two and a half pints of blood flow through the liver each minute.

WorldofTrollcraft, gall or bile is formed in the liver and transported to the GALL (not GULL) bladder which is merely a collective receptacle for bile (gall). It is released from the gall bladder into the duodenum as need arises. Please check your facts before you label people idiots - what goes around....

The liver is NOT the largest organ in the body - the SKIN is Dr dizzo95. Please stop embarrassing us. Otherwise good stuff.

You would get more people here if you had Arny Schwarny read it.

Hello good Dr, while I am not a physician, I do have a U.S. Patent Pending on one of the first ( novel ) artificial liver & ammonia diffuser machines, ( developed and selved in 2000-01 and modeled after a sewage treatment plant,  using slight heating of blood and calcium filters instead of lime filters.

@WorldofTrollcraft Stop throwing religion into the subject of anatomy. I'm Catholic btw. And Catholism has taught me not to push faith onto other people. Want to evangelise? Show love, patience and kindness. But that's besides the point. We're here to learn about the hepatic physiology.
