Blood Flashcards
Functions of blood
carries 02 & nutrients; removes CO2 waste; regulates body temp
Red blood cells aka
erythrocytes
RBCs are produced in the
red bone marrow
Normal RBC count
4-6 million
disorder of low RBC Count
Anemia
increase in RBCs; causes cells to be more thicket
Polycythemia
carries oxygen to the body
hemoglobin
Normal blood components
Yellow (PLASMA 55%) > Buffy Coa (LEUKOCYTES & PLATELETS 1%) > Red (HEMATOCRIT 45 %)
packed red blood cell volume
Hematocrit
WBC (leukocytes) are
Eosinophils (3%), Neutrophils (55%), Basophils (1%), Lymphocytes, Monocytes
make antibodies, T cells and B cells. increased amount in viral infections like AIDS
lymphocytes
largest; destroys germs and eliminate infected cells
monocytes
normal WBC
5-10k
low count
penia
cytosis
high count
platelets; needed for clotting process
thrombocytes
stopping of flow of blood
hemostasis
process of clotting; formation of a bloodclot
coagulation
stationary clot
thrombus
traveling clot
embolus
blood serum
plasma (after centrifugation)
blood type thats a universal recipeint
AB
blood type thats a universal donor
O
inherited protein found on surface of RBCS
rh factor (protein w/ blood Rh+ , blood w/o protein Rh-)
bone marrow produces large amount of abnormal WBCs
Leukemia
RBCs change to a sickle shape & cant carry oxygen; genetic
sickle cell anemia
disease that results in abnormally high # of blood cells, causing blood to thicken
polycythemiavera
form of anemia; causes small , short lived RBCs
Thalassemia
Parasitic infections can be controlled by these WBCs
eosinophils
when a bacterial infection is present, this WBC will be elevated
neutrophils
red blood cells live for anout
4 months
production of RBCs in the blood is controlled by the hormone
erythropietin
WBCs release histamine and heparin and promote inflammation
Basophils
