Document Summary
Connective tissue cells are scattered and make their. Own matrix of collagen, elastin: components of blood. Centrifuged blood formed elements and plasma: plasma rises to top (volume 55%, erythrocytes rbs bottom (volume 45%) known as hematocrit, buffy coat leukocytes and thrombocytes (<1%) Physical characteristics of blood: colour range: Dull red : ph range homeostasis is: 7. 35-7. 45, body temp = 37, blood temp = 38. Need to be familiar with the numbers per mm3: blood volume. Adult male = 5-6l: blood ~ 8% of body weight. Albumin main role is = osmosis. Clotting proteins main role is = plug or clot a cut. Main function is: carries oxygen by means of a chemical called hemoglobin ( hem =iron fe) Erythrocyte anatomy: biconcave disks lost the nucleus and all organelles resulting in shape, bags of hemoglobin, anucleate no nucleus therefore will die within 100-120 days, contain very few organelles. What"s the affect: five million rbcs per cubic millimeter of blood.
