Document Summary
Functions: transport (o2, co2 and nutrients, protection from inflammation, limit spread of infection, destroy microorganisms, etc, regulation fluid balance, stabilize ph, temperature control. Components of blood: blood liquid connective tissues, plasma, plasma proteins albumin, fibrinogen, globulins, dissolved o2, co2, nitrogen, nitrogenous wastes, nutrients, electrolytes, formed elements rbcs, wbcs and platelets, rbc"s erythrocytes. Function to transport o2 to tissues and co2 to lungs. Disc - concave shape, nearly no organelles, lack mitochondria, nucleus and dna. Cytoskeletal proteins spectrin and actin: platelets fragments from special cell in bone marrow, wbc"s granulocytes (neutrophil, eosinophil, basophil) and agranulocytes (lymphocytes and monocytes) Blood viscosity: osmolarity total molarity of dissolved particles that cannot pass through cell wall, alters transfer of fluid between capillaries and tissues, colloid osmotic pressure contribution of proteins, viscosity resistance of fluid flow. Hemoglobin: 4 protein chains 2 beta and 2 alpha, 4 heme groups which bind oxygen at its center fe.
