Blood

hematocrite

also known as packed cell volume and erythrocyte volume fraction

Rh positive

has Rh protein on RBC surface

type B

makes anti- A antibodies

type A

makes anti-B antibodies

type O

makes both anti- A and anti-B antibodies

type AB

makes no antibodies

white blood cells

neutrophils, eosinophils, basophils, lymphocytes, monocytes

Rh negative

no Rh protein on RBC surface, makes Rh- antibidies that can cross placenta

what are the components of blood

plasma (46-63%) formed elements (37-54%)

Plasma

plasma proteins: Albumins, globulins, fibrinogen, regulatory proteins other solutes: electrolytes, organic nutrients, organic wastes

Formed elements

platelets- participate in blood clot formation white blood cells- fight disease causing pathogens red blood cells- transport respiratory gases (O2 and CO2)

universal recipient

type AB and Rh positive

universal donor

type O and Rh negative

list and describe the eight functions of blood

1. transport of respiratory gases 2. regulation of pH 3. regulation of electrolytes 4. regulation of fluid loss, i.e., hemostasis 5. defense against pathogens 6. regulation of body temperature 7. transport of hormones 8. transport of nutrients and metabolic wastes
