what is plasma
liquid part of blood, clear portion with clotting factors, a dilute solution of salts glucose amino acids vitamins urea proteins and fats
what are white blood cells involved in
immune system
what are platelets involved in
blood clotting
what are red blood cells involved in
carrying oxygen
what are the two compartments of blood
plasma and cells
what serum
clear portion without clotting factors
what is the amount of blood in the body
5×10^6/mm3
T/F red blood cells are biconcave discs
true
what is the diameter of red blood cells
7-8um
what is the excess amount of red blood cells called
polycythemia
what are deficient amount of red blood cells called
anemia, macrocytic or megaloblastic, microcytic, hemolytic
how long does it take for red blood cells to synthesis in marrow
2-3 days
what is the order of red blood cell formation
stem cell (hemocytoblast) - committed cell (proerythroblast) - ribosome synthesis (early erythroblast) - hemoglobin accumulation ( lase erythroblast) -normoblast - rejection of nucleus (reticulocyte) - erythrocyte
what are the three main components that red blood cells are composed of
hemoglobin, b-12, iron
what is the job of red blood cells
carry oxygen to the body
what is the size of white blood cells
8 x 10^3/ mm3
what are megakaryocytes
platelets
what is the size of megakaryocytes/platelets
150-300K/ mm3
what are the different kinds of white blood cells
neutrophiles (62%), eosinophils (2.5%), basophils (0.5%), lymphocytes, monocytes
red blood cells, white blood cells and megakaryocytes/platelets are made were
bone marrow (myeloid tissue)
how long do red blood cells circulate in the bloodstream for
100-120 days
T/F can red blood cells twist and change shape
true
what happens when red blood cells become fragile
removed from the spleen
what does hemoglobin molecule provides binding sites for what
O2, Fe, B -12
O2 is attached to what in the hemoglobin molecule
iron
what is the gas exchange in the lungs
O2 in, CO2 out
what to do white blood cells have
nucleus
T/F does white blood cells have hemoglobin
false
how long do white blood cells live for
a few hours or days
what is the formation of lymphocytes
pluripotent stem cells - lymphoid stem cells - lymphoblast - lymphocyte
what is the formation of eosinophils
pluripotent stem cells - myeloid stem cells - eosinophilic myeloblast - eosinophils
what is the formation of basophil
pluripotent stem cells - myeloid stem cells - basophilic myeloblast - basophil
what is the formation of neutrophil
pluripotent stem cells - myeloid stem cells - neutrophilic myeloblast - neutrophil
what is the formation of monocyte
pluripotent stem cells - myeloid stem cells - monoblast - monocyte
what white blood cells are granular
eosinophil, basophil, neutrophil
what white blood cells are agranular
monocyte, lymphocytes
what is the chemotaxis movement of white blood cells
move toward sites of infection or tissue damage in response to chemical signals called chemoattractants.
what is the diapedis movement of white blood cells
squeeze through the walls of blood vessels to exit the bloodstream and migrate into tissues to fight infection or respond to injury
what can to many white blood cells lead to
leukemia AML (acute myeloid leukemia), CML (chronic myeloid leukemia), ALL (acute lymphoblastic leukemia), CLL (chronic lymphoblastic leukemia)
what can to many white blood cells lead to
agranulocytosis or leukopenia
platelets are used for what
clotting around vascular tear
platelets are created where
marrow inside a megakaryocyte
what can abnormal amounts of platelets lead to
thrombocytopenia
what is thrombocytopenia
low platelet count
what exams use Tc-99m labeled red blood cells or ultratag method
RVG cardia imaging, GI bleed studies,liver hemangiomas
what does this image show
MUGA or RVG
what does this image show
Gi bleed (accumulation outside of normal vasculature = bleed
what does this image show liver hemangioma, hot focus in liver = memangioma
what are the methods for red blood cell labeling
in- vitro, modified in vivo, in vivo
what is used for all red blood cell labeling
Tc-99m and cold pyrophosphate kit contents
