erythrocytes
red blood cells
shape and function of a RBC
circular shape that helps make the exchange of oxygen and flow through narrow blood vessels faster
flexible and able to form stacks
hemoglobin
able to bind with oxygen or carbon dioxide that is transferred to the blood
hematocrit
percentage of whole blood volume contributed by red blood cells
doctors like to measure this in a patient’s blood to look out for anemia
anemia
having lower than average hematocrit
erythropoiesis
process of forming red blood cells
where are red blood cells made
in red bone marrow
erythropoietin
needed for successful erthropoiesis
5 specific leukocytes
neutrophil
eosinophil
basophil
monocyte
lymphocyte
leukocytes classified as granulocytes
neutrophil
eosinophil
basophil
leukocytes classified as agranulocytes
monocyte
lymphocyte
neutrophil
phagocytic microphage that comprises 50-70% of all WBC’s
monocyte
phagocytic macrophage
phagocytic microphage
eats small things
phagocytic macrophage
eats large things
basophil
has granules with histamine and heparin that promote inflammation
eosinophil
release toxins and kill parasites
lymphocytes
play an important role in our immune response
3 stages of hemostasis
vascular phase
platelet phase
coagulation phase
vascular phase
vascular spasm occurs
vascular spasm
contraction of smooth muscle reduces width of blood vessel and slows down fluid loss
platelet phase
platelet plug forms
platelet aggregation
platelets accumulate and stick to each other at the exposed injury site
platelet plug
a positive feedback loop stimulates platelet aggregation and the formation of a platelet plug
coagulation phase
blood clot forms
fibrin
sticky protein necessary to form a blood clot
