Document Summary
The cardiovascular system: provides a mechanism for rapid transport of nutrients, waste products, respiratory gases and cells. Blood: fluid connective tissue, functions include, transporting dissolved gases, nutrients, hormones, and metabolic wastes, regulating ph and ion composition of interstitial fluids, restricting fluid loss at injury sites, defending the body against toxins and pathogens, regulating body temperature by absorbing and redistributing heat. The composition of blood: plasma and formed elements comprise whole blood, red blood cells (rbc, white blood cells (wbc, platelets, can fractionate whole blood for analytical or clinical purposes. Hemopoiesis: process of blood cell formation, hemocytoblasts are circulating stem cells that divide to form all types of blood cells, whole blood from anywhere in the body has roughly the same temperature, ph and viscosity. Plasma: accounts for 46-63% of blood volume, 92% of plasma is water, higher concentration of dissolved oxygen and dissolved proteins than interstitial fluid.
