Blood Objectives -list the major components of blood (read fxns of blood in text) -discuss red blood cell structures and oxygen carrying function Discuss ABO blood types -briefly describe the various white blood cells and their functions -Briefly describe platelets -Discuss blood clotting Blood -Major components-Plasma (46-63%), Formed elements (37-54%) 1. Plasma-92% water, 1% other solutes, 7% plasma proteins-mostly produced in the liver Proteins: Albumins (60%)-good for transport of lipids, steroid hormones. Major contributors to osmotic pressure of plasma; Globulins (35%)-transport ions, hormones, lipids; immune function Fibrinogen (4%)-essential component of clotting system; can be converted to insoluble fibrin Serum-plasma without clotting proteins 2. Formed elements (cells and cell fragments)-red blood cells (99.9), white blood cells and platelets (0.1%) -RBC’s-have no nucleus, mitochondria; biconcave shape, which helps them to be stackable, flexible-good for going through small vessels like the capillaries. -most oxygen in blood carried by RBC’s because they contain the protein hemoglobin, which contains 4 HEME molecules-each of which contains an iron atom
