Responsible for circulating blood through the body
Erythrocytes (carry oxygen), leukocytes (immune defense), thrombocytes (clotting)
Arteries
Pump blood away from the heart
Veins
Bring blood to the heart
Atria
Receive Blood
Ventricles
Pump blood out
Right AV Valve – Tricuspid valve (three cusps (flaps))
Left AV Valve – Bicuspid valve (two cusps)
AKA – mitral valve
Right Semilunar Valve – Pulmonary valve
Left Semilunar Valve – Aortic valve
The best image of blood flow is shown above. When blood leaves the pulmonary artery, it is carried to the lungs to become oxygenated. It then re-enters the heart through the pulomanry vein. The aorta then distributes the ovygenated blood to the body.
