Pulmonary valve -Between the right ventricle and pulmonary artery

Mitral Valve -Between the left atrium and left ventricle

Aortic Valve -Between the left ventricle and the aorta

Arteries -Take blood away from the heart, small arteries are called arterioles. most carry oxygenated blood.

Capillaries - microscopic blood vessels where gas exchange occurs; allows O₂ to enter the cells and picks up CO₂ from the cells
