The hepatic vein is a blood vessel that carries deoxygenated blood away from the liver. It collects blood from the liver's smaller veins, known as hepatic venules, and transports it to the inferior vena cava, which then returns the blood to the heart. This process is essential for maintaining proper blood circulation and liver function. The hepatic vein plays a crucial role in the body's metabolism and detoxification processes. As the liver filters toxins and processes nutrients from the digestive system, the hepatic vein ensures that the cleaned blood is sent back into circulation, supporting overall health and well-being.
