Why is the hepatic portal vein so important?

• It carries deoxygenated blood to the liver

• It supplies the liver with glucose for aerobic respiration

• It allows the liver to control the levels of nutrients before they are returned to the blood

• It takes broken down toxins away from the liver

Which of the following are roles of the hepatic portal vein?

I. carries nutrient-rich blood to the liver from the intestine

II. prevents glucose from entering the general circulation immediately

III. supplies the liver with oxygenated blood for aerobic respiration

• I and II only

• I and III only

• II and III only

• I, II and III

Where will blood in the hepatic vein be taken to next?

• vena cava --> left side of heart --> pulmonary artery --> lungs --> right side of heart --> aorta --> hepatic artery

• vena cava --> right side of heart --> pulmonary artery --> lungs --> left side of heart --> aorta --> hepatic artery

• vena cava --> lungs --> left side of heart --> aorta -> hepatic artery

• vena cava --> lungs --> right side of heart --> aorta --> hepatic artery
