Albumins (60%) - transport lipids; steroid hormones, major contributor to osmotic presure of plasma.
Globulins (35) - transport ions, hormones,lipids, immune function.
Fibrinogen (4) - clotting system. converted to fibrin,
reg. proteins - enzymes etc
Blood Type
Type A, B, AB and O.
Type A = surface A antigen, B antibodies
Type B = B antigen, A antibodies
Type AB = A and B antigen. no antibodies
Type O = no antigen. AB antibodies
Rhesus Factor
Rh neg. woman delivers first Rh+ child,fetal + mat. blood mix when placenta breaks down. Rh+ blood sensitizes mother to start producing Rh+ antibodies so during SECOND pregnancy of Rh+ fetus. mat antibodies attack fetal blood cells = hemolytic disease
Vascular Phase
local contraction of a vessel= vascular spasm.
decreases diameter of vessel at site of injury. slows/stops loss of blood thru wall of small vessel. vascular spasm lasts 30 min = vascular phase
Vascular Phase II
-endothelial cells contract and expose underlying basal lamina to blood stream
-EC release chemical factors and local hormones (stimulate smooth mus contractions and division of endothelial cells to repair)
-membranes become sticky (so platelets can ath
Platelet Phase
-platelet adhesion to surface then platelet aggregation as more platelets stick together which forms a platelet plug
