New cards
49

Comprised of two leaflets - allows bloodflow from left atrium to left ventricle

Mitral Valve

New cards
50

Pumps oxygenated blood to the body via the aorta

Left Ventricle

New cards
51

Comprised of three leaflets - allows blood flow from the left ventricle into the ascending aorta

Aortic Valve

New cards
52

Supply blood to the cardiac muscle
