Circulatory System Organs - TSV
The circulatory system (cardiovascular system) is an organ system that delivers blood throughout the body, consisting of the heart and blood vessels (arteries, veins, and capillaries). The heart functions as a pump that sends blood out, while blood vessels serve as pathways for blood transport. It plays a crucial role in supplying oxygen and nutrients to cells throughout the body and collecting carbon dioxide and waste products.
