What is the function of portal vein?

Functions of the Portal Vein

1. Collects blood from the digestive organs. The portal vein collects blood from the stomach, small intestine, pancreas, and spleen. This blood is rich in nutrients that have been absorbed from the digestive tract.

2. Delivers blood to the liver. The portal vein carries the nutrient-rich blood to the liver. The liver then filters the blood and removes any harmful substances.

3. Stores nutrients. The liver stores nutrients that are not immediately needed by the body. These nutrients can be released into the bloodstream when needed.

4. Produces bile. The liver produces bile, which is a substance that helps to digest fats. Bile is stored in the gallbladder and released into the small intestine when needed.

The portal vein is an important part of the digestive system. It helps to ensure that the body receives the nutrients it needs and that harmful substances are removed from the blood.
