Cardiovascular circulation refers to the movement of blood throughout the body, facilitated by the heart, blood vessels, and blood. The heart pumps oxygen-rich blood from the left side to the body through arteries, delivering essential nutrients and oxygen to tissues. Afterward, the blood returns to the heart through veins, carrying carbon dioxide and waste products. This system is crucial for maintaining overall health, as it ensures that every cell receives the necessary substances for energy and function. The circulatory system also plays a role in regulating body temperature and transporting hormones, making it vital for homeostasis.
