What is the flow of nutrient-rich blood from the digestive organs to the liver called?

The flow of nutrient-rich blood from the digestive organs to the liver is known as portal circulation. This process is specifically facilitated by the hepatic portal vein, which collects blood that has absorbed nutrients from the stomach and intestines and transports it to the liver. The liver processes these nutrients, detoxifies harmful substances, and regulates the distribution of nutrients throughout the body.

In contrast, coronary circulation refers to the flow of blood specifically to and from the tissues of the heart muscle itself. Systemic circulation involves the movement of oxygenated blood away from the heart to the rest of the body and the return of deoxygenated blood back to the heart. Renal circulation pertains to the flow of blood to and from the kidneys. These other circulatory routes serve different functions and are not involved in the nutrient transport from the digestive organs to the liver.
