Liver Structure and Function

Which blood vessel carries deoxygenated blood away from the liver?

• hepatic artery

• hepatic vein

• hepatic portal vein

• aorta

Which blood vessel carries oxygenated blood to the liver?

• hepatic vein

• vena cava

• hepatic artery

• hepatic portal vein

Which of the following is true of the hepatic portal vein?

I. it carries deoxygenated blood

II. it helps maintain the osmotic potential of blood

III. it takes blood from the heart to the liver

• I and II only

• I and III only

• II and III only

• I, II and III

Lactate (lactic acid) is taken to the liver to be broken down.

Which blood vessel would carry lactate to the liver?

• hepatic artery

• hepatic portal vein

• hepatic vein

• vena cava

Which blood vessel does the hepatic artery branch off from?

• pulmonary vein

• pulmonary artery

• vena cava

• aorta

Which blood vessel does the hepatic vein lead into?

• vena cava

• pulmonary vein

• aorta

• pulmonary artery

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

Which of the following are true of a sinusoid?

I. it is involved in the exchange of materials between hepatocytes and blood

II. Kupffer cells contain microvilli for faster exchange

III. blood from the hepatic artery and hepatic portal vein mixes within it

• I and II only

• I and III only

• II and III only

• I, II and III
