Answer |
| Plasma Composition | 55%plasma; 7% proteins; 1% other solutes; 92% water |
| Plasma Proteins | 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 |
