Presentation Transcript

  1. Cardiovascular

  2. Blood Vessels • 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

  3. Blood Flow Through the Heart 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 www.youtube.com/watch?v=SvAVu-7E2gA
