Document Summary

Blood is the only fluid tissue in the body; it is formed elements suspended in plasma. Most of the formed elements are short-lived/disposable and are replaced by bone marrow. Colour is scarlet(oxygen rich) to dark red(oxygen poor). Ph = 7. 35-7. 45 and temperature is 38 c. Makes up 8% of body weight(5-6 litres for boys and 4-5 litres for girls). The buffy coat: made of leukocytes and platelets and makes of up of less than 1% of whole blood. Erythrocytes: make up 45% of whole blood(hematocrit) and is the most dense component. Plasma proteins: produced in the liver and are functional proteins which remain in blood. Albumin: the main protein found in plasma and it functions to regulate the osmotic pressure of blood. Describe the functional anatomy of an erythrocyte, the structural organization of hemoglobin. The erythrocyte is 7. 5um in diameter and are in the shape of biconcave discs(no nucleus). Other proteins maintain the plasma membrane and regulate cell shape.
