Blood pressure in the mammalian aorta is maximum during:
Correct answer: A. Systole of the left ventricle
- A. Systole of the left ventricle
- B. Diastole of the right atrium
- C. Systole of the left atrium
- D. Diastole of the right ventricle.
Explanation
During systole, the heart muscle contracts, and blood is pumped out of the left ventricle into the aorta, which is the largest artery in the body. This contraction generates high pressure, resulting in the maximum blood pressure in the mammalian aorta. The left ventricle is responsible for pumping oxygenated blood to the rest of the body, so its systolic contraction produces a surge of blood that increases the pressure in the aorta.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
