What is "circulation"?
Circulation refers to the continuous movement of blood throughout the cardiovascular system. It is driven by the rhythmic contractions of the heart and facilitated by a network of blood vessels, including arteries, veins, and capillaries. Circulation ensures the delivery of oxygen, nutrients, hormones, and other vital substances to all tissues and organs while removing waste products and carbon dioxide. It plays a vital role in maintaining cellular function, supporting organ systems, regulating body temperature, and facilitating the immune response. Proper circulation is essential for overall health and well-being.
