THE BLOOD
Hemostasis
-
-
Platelets flow --> bloodstream. cannot adhere to a blood vessel unless there is a tear or damage to that blood vessel
-

-
Erythrocytes
-
Hemoglobin
protein, a red pigment molecule containing iron
-
red bone marrow -->myeloid stem cell. --> mitotic division --> erythroblast. the nucleus carry oxygen. This is important as it allows more gas exchange to occur. Small

-
Leukocytes
White blood cells,fight infection, remove toxins debris. travel by emigration.
Granulocytes
granules in cytoplasm, PHIL. neutrophils, eosinophils and the basophils

-
Formation
living blood cells erythrocytes, leukocytes, and platelets
hematopiesis
-
Myeloid stem cell
precurser, platlets, erythocytes, 4 leukocytes

-
Thrombus
aggregation of platelets, red blood cells &white blood cells -->fibrin strands. Attach--> vessel wall = slow down flow of blood /or block
Embolus
(blood clot/ thrombus) moving within blood freely, if attached long enough to vessels=Large. Can block blood flow to organs
