Clues

  • At rest the arterioles to the muscles: the arterioles ... and the pre capillary sphincters ... decreasing blood flow (13, 6)
  • Connect capillaries to veins; smaller versions than veins, without valves (7)
  • During exercise the arterioles to the organs ... and the pre capillary sphincters ... this decreases the blood flow (13, 5)
  • Greatest number of times your heart can beat in a minute (5, 4)
  • Large vessels that carry blood away from the heart (6)
  • The space inside an artery, vein or capillary, through which blood passes (5)
  • The transport of deoxygenated blood from the capillaries, through the venules and veins and back to the right atrium of the heart via the vena cava (6, 6)
  • The volume of blood pumped from the heart in one minute (7, 6)
  • Vessels that are one cell thick (9)
  • Vessels that connect arteries to capillaries; they are smaller versions of arteries, with muscular walls (10)
