The function of hemoglobin is to
carry dissolved blood gases
________ involves a cascade of reactions leading to the conversion of fibrinogen to fibrin.
coagulation
A moving blood clot is called a(n)
embolus
White blood cells that are increased in allergic individuals are
eosinophils
red blood cell production is regulated by the hormone
erythropoietin
The yellow color that is visible in the eyes and skin in jaundice results from
excessive amounts of bilirubin in the plasma extensive breakdown of RBCs the recycling of hemoglobin destruction of hemoglobin.
Some rat poisons contain a toxin that blocks the liver's ability to utilize vitamin K. Animals that consume this poison would die of

A hematocrit provides information on
sedimentation rate
