Functions of blood: blood is the life-sustaining transport vehicle of the cardiovascular system, functions include, transport, regulation, protection. Transport: transport functions include, delivering o2 and nutrients to body cells, transporting metabolic wastes to lungs and kidneys for elimination, transporting hormones from endocrine organs to target organs. Regulation: regulation functions include, maintaining body temperature by absorbing and distributing heat, maintaining normal ph using buffers; alkaline reserve of bicarbonate ions, maintaining adequate fluid volume in circulatory system.
