Cardiovascular System Components
Cardiovascular System Components
The heart, blood vessels (arteries, veins, capillaries), and blood, working together to circulate blood throughout the body.
Heart Chambers
Heart Chambers
The heart has four chambers: two atria (receiving chambers) and two ventricles (pumping chambers).
Heart Valves
Heart Valves
Tricuspid, pulmonary semilunar, mitral/bicuspid, and aortic semilunar valves control blood flow direction and prevent backflow in the heart.
