Document Summary
Regulates body temperature, ph in body tissues, adequate fluid. Blood plasma serum is plasma where the clotting factor hasn"t been removed. Hematocrit (percentage of rbc in whole blood) Plasma proteins are mostly produced in the liver (except gamma globulins) Albumin is a carrier of various molecules, an important blood buffer, and major osmotic protein (60% of all plasma proteins) Doesn"t have a nucleus or any organelles. Don"t grow, don"t divide, don"t created new proteins. Spectrin attaches to cytoplasmic surface, provide structure but are flexible. Hemoglobin makes up 97% of cell volume. Have no mitochondria therefore atp production is anaerobic so they don"t consume oxygen. Hemoglobin= protein globin bound to red heme pigment. Keeps it from fragmenting and being lost. Keeps it from contributing directly to osmotic pressure and blood viscosity. The cite of where the cells are produced changes as you age. Hematopoietic stem cell (hemocytoblast): stem cell for all formed elements cells become committed to a particular pathway.
