And the units of renal clearance are milliliters the volume per minute, our time. So let's begin by taking a look at the simplified diagram of our nephron, the basic functional unit of our kidney. So we have the apharyine arterial that brings our blood vessels, that brings the blood plasma into the network of capillaries found inside the bow, its capsule known as the glomerylus. Now, within this network of capillaries, we have filtration taking place. Some portion of the blood plasma that enters the glomerylus is filtered through a filtration membrane and into the Bowman's capital or the Bowman space of the Bowman's capsule and then enters our tubular section of the nephron, which includes the proximal convolute tubule, the lupus henley, the distal convolute, as well as the collecting duct. Now, within the tubular section, we also have reabsorption and secretion taking place.
