Question 11

A human heart has four chambers and four valves to regulate the process of blood circulation in the body. What kind of phases would occur when blood is supplied to Aorta and Pulmonary Artery from the chambers of the heart ?

  1. Atrial systole and ventricular diastole.
  2. Ventricular systole and Atrial diastole.
  3. Right ventricular systole and left ventricular diastole.
  4. Left atrial systole and right atrial diastole.
Answer

Ventricular systole and Atrial diastole

Reason

When blood is supplied to aorta and pulmonary artery the ventricles contracts in order to pump blood out of the ventricles, meanwhile the atria relaxes and receives blood from vena cava and pulmonary vein.
