nutrients in the hepatic artery   _____________ nutrients in the hepatic portal vein	Answer 5Choose...greater thanequal toless than
maximum pressure in the left ventricle ______________ maximum pressure in the aorta

Answer 1

1. Greater than. Pulmonary vein is rich in oxygen content since the transfusion occurs in the lungs and the fresh oxygen rich blood is carried to the heart.

2.Equal to. Maximum pressure in the aorta is equal to the maximum pressure in the left atrium., about 120 mmHg. At the end of diastole, the aortic pressure is about 80 mm Hg. When left ventricular contraction occurs, aortic valves open and the pressure increases to 120 mmHg.

3.Greater than than. Blood flow through the lungs is greater than the blood flow throgh the kidney.

4.Greater than. Blood flow through the dilated vessel is greater than blood flow through the constricted vessel.

5.Less than. Hepatic artery carries blood from the aorta the liver.Hepatic portal vein carries blood containing digested nutrients from the GIT.

6.Greter than. Maximum pressure in the ventricle is about 120 mm Hg - 140 mmHg. Whereas Maximum pressure in the aorta is about 120 mmHg.
