Blood pressure in the mammalian aorta is maximum during

Blood pressure in the mammalian aorta is maximum during

Options

  1. Asystole of the left atrium
  2. Bdiastole of the right ventricle
  3. Csystole of the left ventricle
  4. Ddiastole of the right atrium

Correct answer

C. systole of the left ventricle

Step-by-step solution

Left ventricle drives blood into the aorta during the ventricular systole. Aorta receives blood directly from ventricles and supplies blood to all the body parts. The greater the stroke volume, the greater the change in the aortic pressure. Hence, blood pressure in aorta will be maximum when left ventricle pumps the blood into the aorta.
