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.

    @pelsjoem our skin isn't inside us – the liver is. if you said that as your answer you'd undoubtedly get it wrong.

    Ofcourse the skin is the largest and heaviest organ of the body, and not the liver.

    I do agree of course with that the skin is the largest organ of the body but I'm not so sure about the semantical grammar of English. The movie says IN the body not OF the body. But I guess they made the mistake you all pointed out.

    True.. the skin is the largest organ, while the liver is merely the largest INTERNAL organ in the body

    I can see how someone would make the natural mistake of thinking that the liver is the largest organ. You see it is very simple, every fucking thing is a damn organ! Even blood vessels are part of the larger vascular organ. Due to this fact the term holds absolutely no meaning and is worthless to even use as it means nothing.

    No. It's an organ. An organ is made up of different tissues working together. Skin has many tissue like the epithelial tissue, connective tissue and things. Also, organs make up organ systems, just like skin is a part of the integumentary system.

    Saying it's the largest organ in the body might confuse people if they're asked "What is the biggest organ?"

    When we talk about being in the body, it really depends on your definition of the body. When you say in the body, do you mean inside of what we see to be our body, or in the body's system?

    When the first line of the video is false, it sets up a poor outlook for the rest of it…the largest organ in the body? At least if you are going to say that, explain your reasoning: largest in terms of complexity? Largest peritoneal organ? Largest digestive organ? Largest in terms of necessity for homeostasis? Or even hemostasis? It definitely isn't the largest organ. This was on TV so you know people will believe it. If it's on TV it's gotta be true!
