The body system responsible for circulation of the blood, including the heart, arteries, veins and capillaries, is called the cardiovascular system
<h3>Cardiovascular system</h3>
To supply the lungs with oxygen, the circulatory system (cardiovascular system) pumps blood from the heart. Following that, the heart pumps oxygen-rich blood through arteries to the rest of the body. Poor in oxygen blood is returned to the heart by veins to restart the circulatory system. The cardiovascular system plays a crucial role in supplying your body with oxygen and nutrients as well as removing waste. Your cardiovascular system is how your cells obtain the nutrients they require to function properly. It is crucial to take care of your heart by exercising, eating a healthy diet, and maintaining under control your blood pressure and cholesterol.
