PY - 2015 T2 - Medical Physiology: The Big Picture AB - Blood circulates within the cardiovascular system to provide a vehicle for the distribution of respiratory gases, nutrients, water, electrolytes, hormones, antibodies, drugs, metabolic waste, and heat throughout the body. Most of the major negative feedback control systems of the body defend normal blood composition (e.g., blood glucose concentration, blood volume, and arterial O2 partial pressure). Blood is composed of cellular elements (i.e., red blood cells, white blood cells, and platelets), which are suspended in blood plasma. A person who weighs 70 kg has approximately 5 L of blood, of which about 2 L is occupied by the formed cellular elements and 3 L is plasma.
