Document Summary
The blood: blood is a connective tissue consisting of a matrix called plasma and a cellular portion called formed elements. Hematocrit: % of red blood cells (erythrocytes) in the blood volume. O2, co2, nutrients, metabolic waste, heat, cells, and hormones body ph, body temperature, and water in fluid compartments. Functions of the blood: transports, regulates, protects, against blood loss through clotting, against diseases through phagocytic white blood cells and antibodies limits infection thus controlling inflammation. Albumins (60%) responsible for osmotic pressure in the blood transport lipid, hormones, calcium and other solute buffer blood ph. Globulins (36%) transport lipids defense (gamma globulins antibodies) Erythrocytes (rbc: biconcave, disc shape o each rbc contains. 250 million hemoglobin: mature erythrocytes are anucleate and have no cell organelles, lack mitochondria use anaerobic formation of atp, cannot repair, because has no ribosomes or nucleus to make proteins. Hgb also transports 5% of co2 by binding it to amino groups on globin proteins.
