Document Summary
Albumin consist of 60% of all plasma protein. 45% of blood are rbcs and the rest is plasma. Leukocytes are the only complete cell in blood because they have a nucleus. Spectrin is the cytoskeleton that holds the shape of rbcs. Oxygen combines with heme group, but carbon dioxide combines with globin. Hematopoietic is the stem cell for all blood cells. Hematopoiesis is the production of blood cells in bone marrow. Rbc are created 2million/sec and last about 120 days. Spleen = rbc graveyard, iron stored and reused, rest of heme degraded to bile. Body stops bleeding upon injury to maintain blood in the fluid state with vessel integrity. Serotonin and thromboxane enhances vascular spasm and aggregation. Intrinsic pathway: expose underlying tissue such as collagen. Platelets cling to the surface and their surfaces provide for mobilization of factors. Pf3 released by aggregated platelets, resulting in prothrombin activator. Prothrombin is released that then turns into thrombin.
