Which part of the heart is known as the Left Ventricle that helps to supply oxygenated blood to almost the whole body?
Correct answer: A. 6
- A. 6
- B. 1
- C. 3
- D. 4
Explanation
The left ventricle of the heart is located at position 6 in the figure. It is responsible for pumping oxygenated blood to the entire body through the aorta. This thick-walled and muscular chamber generates high pressure to maintain blood flow throughout the body. Other marked points include the superior vena cava (2), which brings deoxygenated blood from the upper body to the right atrium of the heart. The aorta (1) carries oxygenated blood from the left ventricle to the rest of the body. The right atrium (3) receives deoxygenated blood from the body and pumps it into the right ventricle. The tricuspid valve (4) separates the right atrium and right ventricle. The right ventricle (5) is the chamber of the heart that receives deoxygenated blood from the right atrium and pumps it to the lungs for oxygenation, while the bicuspid valve (7) separates the left atrium and left ventricle.

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.
