 Arteries: largest blood vessel; carries blood away from the heart; bright red blood; blood spurts out  Veins: carries blood back to the heart; darker red blood; blood flows out  Capillaries: smallest blood vessels

Capillaries --- venules --- veins --- vena cava (caudal/cranial) --- right atrium --- tricuspid valve (right AV valve) --- right ventricle --- pulmonary semilunar valve --- pulmonary artery - -- lung --- pulmonary vein --- left atrium --- bicuspid valve (left AV valve, mitral valve) --- left ventricle --- aortic semilunar valve --- aorta --- artery --- arterioles --- capillaries Blood Flow Song
