Fluid connective tissue composed of plasma and formed elements: erythrocytes (rbc"s), leukocytes (wbc"s) and platelets. Matrix is plasma and the living blood cells are formed elements. Buffy coat: less than 1% of blood leukocytes and platelets. Colour varies with o2 content: high: scarlet red, low: dark levels ph: 7. 35-7. 45. 8% of body weight (females 4-5l and males 5-6l) Delivering o2 from lungs and nutrients from digestive tract to all body cells. Transports all metabolic wastes from cells for elimination (lungs dispose of co2 and kidneys dispose nitrogenous wastes) Transports hormones from endocrine glands to target organs: regulation. Body temperature: by absorbing and distributing heat throughout the body. Normal ph: blood proteins and solutes act as buffers to prevent vast changes in blood ph, acts as a reservoir of bicarbonate ions. Fluid volume: blood proteins prevent excessive fluid loss from bloodstream to tissue spaces, fluid vol. remains ample to support circulation: protection.
