👉 The chapter veins, also known as the venous plexuses or sinus venosus, are a network of small veins that drain blood from the liver and spleen into the inferior vena cava. These veins are located beneath the liver's surface and are part of the hepatic portal system, which transports nutrient-rich blood from the digestive organs to the liver for processing before it enters the systemic circulation. The chapter veins are named after the German anatomist Ernst V. Vein, who first described them in 1859. They play a crucial role in the liver's function and overall circulatory system.
