Blood volume in adults
Male = 5-6 liters
Female = 4-5 liters
Total Blood volume is equal to . . . .
. . . . ~ 7% of body weight
% of formed elements that are RBC
99.9%
RBC Count in adults
Males = 4.5 -6.3 million/cubic mm
Females = 4.2-5.5 million/cubic mm
Life span of RBC
120 days
Carbaminohemoglobin - desc
When O2 levels are low, oxygen is released. The heme molecules then pick up the CO2 that has built up in the system and transports it to the lungs. In the capillaries of the lungs, the CO2 is released and O2 is picked up and transported to peripheral tissues
Anemia - desc
Condition caused by Iow levels of hematocrit and/or Hb.
Diminished oxygen in the system
Anemia - symptoms
weakness
lethargy
confusion
chronic fatigue
Blood Types - def'n
classification based on the presence or absence of surface antigens
Three major surface antigens found on RBCs
A
B
Rh
Type A has __ surface antigen
Type A has _A_ surface antigen
Type B has __ surface antigen
Type B has _B_ surface antigen
Type AB has ___ surface antigen
Type AB has _A&B_ surface antigen
Type O has ___ surface antigen
Type O has _no_ surface antigen
Agglutinogens - def'n
Surface antigens on your own RBCs
Agglutination - def'n
Agglutins attack antigens on foreign RBCs
Neutrophils - % of WBCs
50–70%
Neutrophils - func'n
first to attack bacteria
Eosinophils - % of WBCs
2–4%
Eosinophils - func'n
Attack large parasites
Basophils - % of WBCs
< 1%
Basophils - func'n
Release histamine - Dilates blood vessels
Release heparin - Prevents blood clotting
Monocytes - % of WBCs
2–8%
Monocytes - func'n
become macrophages
Lymphocytes - % of WBCs
20–30%
Lymphocytes - func'n
part of the body’s specific defense system
Classes of Lymphocytes - list
T cells
B cells
NK cells
T Cells - desc
Cell-mediated immunity
Attack foreign cells directly
B cells - desc
Humoral immunity
Differentiate into plasma cells
