Final answer:
The hepatic sinusoids are the site of exchange between the hepatocytes and the blood.
Step-by-step explanation:
The hepatic sinusoids are the site of exchange between hepatocytes and the blood, allowing for processing of nutrients, toxins, and waste materials. The lobules are arrangements around the perimeter of hepatic lobules that support the functions of the liver.
They are open, porous spaces formed by fenestrated capillaries from hepatic portal veins and hepatic arteries. The sinusoids allow hepatocytes to process nutrients, toxins, and waste materials carried by the blood. Blood and bile flow in opposite directions in the sinusoids, and they also contain phagocytes called Kupffer cells that remove foreign materials.
The lobules, on the other hand, are distinctive arrangements around the perimeter of hepatic lobules, consisting of a bile duct, a hepatic artery branch, and a hepatic portal vein branch. These structures in the portal triad work together to support the functions of the liver.
