What does the cardiovascular system do?

The cardiovascular system plays a crucial role in the human body primarily by moving blood throughout the body. This transportation system is responsible for delivering oxygen and nutrients to cells and tissues, while also removing waste products like carbon dioxide. The heart acts as the pump that drives this circulation, pushing blood through a network of arteries, veins, and capillaries.

In addition, the cardiovascular system helps maintain homeostasis by regulating body temperature and pH levels, contributing to the overall stability of the internal environment. This system is integral to the body's response to exercise, stress, and other physiological needs by adjusting blood flow accordingly. Effective circulation is essential for overall health, as it ensures that all body systems receive the necessary support for proper function.
