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. Now, the rest of that blood plasma that is not filter travels into the Ethernet arterial that then enters our peritubular capillaries. And these are the capillaries where we have reabsorption and secretion taking place between the blood capillaries and our tubules of the nephron. Now, let's begin by discussing the rate at which blood actually flows into the nephron for normal kidneys.
