The difference in renal vascular resistance between two points in time or two conditions expressed as the result of the subtraction in and of itself without comparison by ratio with another quantity. 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.
