The sinusoids of the liver transport a mixture of materials, primarily blood that contains nutrients, hormones, and metabolic waste products. This blood comes from both the hepatic artery and the portal vein, bringing oxygen and nutrient-rich substances from the intestine. Additionally, the sinusoids facilitate the exchange of substances between the blood and liver cells, aiding in processes such as detoxification and metabolism.

Sinusoids
Kupffer cells are specialized macrophages found in the liver, specifically within the sinusoids, which are specialized blood vessels in the liver. They play a key role in the immune system by removing debris, pathogens, and other foreign particles from the blood passing through the liver.
The liver contains lobules with sinusoids that lead to a central vein called the central vein or hepatic vein. Each lobule is made up of hepatic cells (hepatocytes) arranged around a central vein, which functions to drain blood from the sinusoids in the lobule.
the vessel that carries blood between the intestinal capillaries and the sinusoids of the liver.
Kupffer cells are specialised macrophages that are found in the sinusoids of the liver.
In the center of a liver lobule, there is a central vein. This area collects the blood that contains liver sinusoids. That blood is then filtered back to the hepatic vein.
Hepatic macrophages are special phagocytic cells, also called Kupffer cells, that line the sinusoids and remove debris from the blood.
The substance that is transported from the liver to the kidneys is urea. Urea is produced in the liver during the breakdown of proteins and is transported through the blood to the kidneys for excretion in the urine.
Sinusoids are a type of blood vessel that allows for nutrient exchange between blood and tissues, particularly in organs like the liver and spleen. They also help to regulate blood flow and maintain proper pressure in these organs.
