2.Describe the functioning and relative amounts of the components of blood, including:Red blood cells(Erythrocytes) (99%)Hemoglobin (heme, globin, Fe+)a.Transport oxygenb.4polypeptide subunits-> holds 4 O2 totalheme group: each holds 1 O2-Fe atomc. red pigment, give blood its color-carrying more oxygen-> brighter red- oxygen deficient-> lighter redd. oxyhemoglobin- full of 4 O2e. deoxyhemoglobin- not full (0,1,2,3, O2)White blood cells (Leukocytes)(1%)1) Granulocytes- granules in cytoplasm-neutrophil (70%): multi lobed nucleus-phagocytes consume bacteria-eosinophil (4%): bi lobed nucleus, stain red/orange-fight parasitic worms, allergies-basophil (1%): irregular nucleus, stain deep blue/purple-histamine: vasodilator (dilates blood vessels) during inflammation-heparin: blood thinner, reduce blood clot after damage is fixed2) Agranulocyte- NO granules-lymphocytes (20%): large nucleus, little cytoplasm-adaptive immunity: T and B cells-monocytes (5%): large cells, kidney-shaped nucleus-migrate into tissues and become macrophagesPlasma(55%)Water(92%)Plasma proteins (7%)types of plasma proteins:-albumins: transport lipids, osmotic balance-globulins: transport lipids, antibody -fibrinogen: coagulation (clotting)Nutrients, wastes (1%)-O2,CO2,H+, K+, Na+, Ca2+, HCO3-, AA, monosaccs (all dissolved in water)Platelets
