When left ventricle contracts, it pushes the blood through_to all parts of the body.
Correct answer: A. Aorta
- A. Aorta
- B. Pulmonary trunk
- C. Pulmonary artery
- D. Pulmonary vein
Explanation
When the left ventricle contracts, it pushes the blood through the aortic valve into the aorta and then to all parts of the body. The aortic valve is located at the base of the aorta, the largest artery in the body, which arises from the left ventricle of the heart. As the left ventricle contracts during systole, the aortic valve opens, allowing oxygen-rich blood to be ejected from the heart and into the aorta. From there, the blood is distributed through the systemic circulation, reaching and supplying oxygen and nutrients to all organs and tissues in the body. This process is essential for delivering oxygenated blood to meet the metabolic demands of the body's cells and ensure proper functioning of various organs.

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.
