greater number of red blood cells increases the hemoglobin concentration, which
in turn increases the oxygen -carrying capacity per unit volume of
blood(Molinar,219).” This then increases the oxygen sent to the tissues.
Respiration and cardiac output are also increased. There is an increase in the
capillary network to aid ...
