The vena cava brings blood loaded with carbon dioxide to the ______________ (chamber).
After passing through
the
_________(atrioventricular
valves)
the
blood falls into
the___________(chamber). This chamber pumps the carbon dioxide loaded blood through the
___________ (semilunar valves) to the _________(blood vessels) . These arteries take the
blood to the __________ where the blood gives up its carbon dioxide and takes
in________________. The blood then returns to the heart through the __________(blood
vessels) and enters the ___________(chamber). The blood then passes through the ________
(atrioventricular valves) and falls into the_________(chamber). This chamber pumps the blood
through the aortic semilunar valves into the____________(blood vessels) which delivers
oxygenated blood to all parts of the body.
