GENERAL HISTOLOGY

Detailed explanation-1: -In the liver the blood from the portal vein flows through a network of microscopic vessels called sinusoids in which the blood is relieved of worn-out red cells, bacteria, and other debris and in which nutrients are added to the blood or removed from it for storage.…

Detailed explanation-2: -Sinusoids, small blood vessels between the radiating rows of hepatocytes, convey oxygen-rich hepatic arterial blood and nutrient-rich portal venous blood to the hepatocytes and eventually drain into the central vein, which drains into the hepatic vein.

Detailed explanation-3: -Kupffer cells are resident liver macrophages and play a critical role in maintaining liver functions. Under physiological conditions, they are the first innate immune cells and protect the liver from bacterial infections.
