B Correct answer
Explanation

In order for the heart to deliver oxygenated blood to all cells, blood is pumped through arteries. Veins bring deoxygenated blood cells to the lungs, which are oxygenated and sent back to heart. In this way, a continuous cycle is formed by pumping oxygenated blood and deoxygenated blood out to their designated destinations. Therefore, the heart helps to maintain the circulatory system.
