2. Describe the functioning and relative amounts of the components of blood, including: Red blood cells (Erythrocytes) (99%) Hemoglobin (heme, globin, Fe+) a. Transport oxygen b. 4polypeptide subunits-> holds 4 O2 total heme group: each holds 1 O2 -Fe atom c. red pigment, give blood its color -carrying more oxygen-> brighter red - oxygen deficient-> lighter red d. oxyhemoglobin- full of 4 O2 e. 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 fixed 2) 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 macrophages Plasma (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
