The term "central veins of liver" refers to the veins that carry blood out of the liver lobules. In terms of spelling, "central" is pronounced /ˈsɛn.trəl/ with emphasis on the first syllable and the "tr" pronounced as a separate sound. "Veins" is pronounced /veɪnz/ with a long "a" sound in the first syllable and emphasis on the second syllable. "Liver" is pronounced /ˈlɪ.vər/ with emphasis on the first syllable and a "v" sound replacing the "f" in "lifer."
The central veins of the liver are a system of blood vessels located at the center of the liver lobules. The liver is a vital organ that performs various functions, including detoxification, metabolism, and synthesis of essential molecules. These central veins play a critical role in the blood supply and drainage within the liver.
The central veins are interconnected and form a network known as the central venous system. They receive blood from the sinusoids, which are small capillaries within the liver lobules. The sinusoids receive blood from both the hepatic artery and the portal vein, which carry oxygenated and nutrient-rich blood to the liver, respectively.
As blood flows through the sinusoids, it picks up various substances, such as toxins and metabolic byproducts, that need to be detoxified or filtered out by the liver. This blood then converges into the central veins, which eventually merge to form larger hepatic veins. The hepatic veins then carry the deoxygenated and purified blood away from the liver and back towards the heart for circulation throughout the body.
The central veins' location at the core of the liver lobules allows for efficient blood drainage and transport of filtered blood for systemic distribution. Their function is crucial for maintaining overall liver health and facilitating the liver's essential metabolic processes.
