Plasma
Location
composition
Fuction
Non cellular (liquid) portion of blood
Part of ECF
>90% water
Transport CO2, nutrients, waste prod, hormones
Hemostasis
A function of blood: Prevention of blood loss
Hematocrit
Composition
% of total blood volume occupied by packed red blood cells
x/y x 100% (rbs/total whole blood)
F : 42 +/- 5%
M : 47 +/- 5%
Anemia
«_space;45% rbc»_space;55% plasma
Polycythemia
Blood is more viscous- when in higher altitude or from athletes doing blood doping
» 45% rbc «55% plasma
Intracellular fluid (ICF)
Fluid inside of cells
Extracellular fluid
Fluid outside of cells
= Plasma + Interstitial fluid
Plasma proteins
Fxns
Albumins- Liver
Globulins- Liver & Lymphoid tissue
