Document Summary

Only fluid tissue in body (formed elements suspended in plasma) Formed elements: wbc, rbc, platelets: fragments of cells. Colour is scarlet when oxygenated, and dark red/maroon when deoxygenated. More dense, viscous than water ph of 7. 35-7. 45; about 28 degrees celsius. 8% body weight (5-6l for males and 4-5l for females) Functions associated with blood and the circulatory system. Distribution: oxygen and nutrients, metabolic wastes for disposal, hormones. Regulation: body temperature: distribution, conservation, dissipation, ph in body tissues (plasma, proteins, bicarbonate reserve, adequate fluid volume. Protection: platelets, plasma proteins, blood clotting, antibodies, complement (destruction of foreign agents), wbcs. Straw-coloured; 90% water and many solutes ** table 17. 1. Plasma proteins: produced in liver (except gamma globulins); functional proteins which remain in blood. Osmotic ion: an ion what draws water to itself (na+) Blood constantly adjusted to keep its composition, ph within normal range. Erythrocytes: many more abundant than wbc: cells because no organelles.
