Document Summary

Average volume: women: 5l (hematocrit = 42%, men 5. 5l (hematocrit = 45%) 3 types of specialized cells: erythrocytes: rbc, o2 transport, leukocytes: wbc, platelets (thrombocytes): cell fragments, hemostasis. Packed cell volume (hematocrit: buffy coat (platelets and leukocytes) = <1% of whole blood, erythrocytes (rbc) = 45% of whole blood. 55% plasma: 90% h2o, 7% plasma proteins, 3% other. 45% formed elements: >99% rbc, <1% wbc and platelets. Hematocrit = 45% formed elements/100% total blood volume = 45. Membrane excitability, fluid distribution (osmosis ecf/icf), na+ and cl- most abundant, Osmotic effect of ecf btwn vascular and interstitial compartments, ph changes. Transport water-insoluble substances (clotting factors, inactive precursor molecules) Do not diffuse through capillary wall > osmotic pressure. Made by liver (all except gamma globulins > produced by lymphocytes) All rbc, 5 billion rbc in 1ml of blood (5x106/mm3) Shape optimal for o2 transportation: large surface area and thinness for diffusion of o2, flexible (8um cell > 3um capillaries)
