calculated renal vascular resistance slope of contraction-induced renal vascular resistance curve 2013-11-18T17:27:01Z A calculated measurement of the slope, the ratio of vertical change to horizontal change, of the line of a graph designating the change in renal vascular resistance in response to a drug or other condition which causes constriction or reduction of the interior diameter of blood vessels. Renal vascular resistance is the degree to which the blood vessels of the kidneys impede the flow of blood through them. Blood vessels are the network of muscular tubes that carry blood throughout the body. Blood is the fluid that circulates through the heart, arteries, capillaries and veins carrying nutrients and oxygen to the body tissues and metabolites away from them. Kidney is the paired organ which functions to maintain proper water and electrolyte balance, regulate acid-base concentration, and filter the blood of metabolic wastes.
