Document Summary
Module 11 renal system. By the end of this section, you should be able to: Located within the renal pyramids are the functional units of the kidneys the nephrons. Each nephron drains through a collecting duct into a calyx. Anatomy blood supply of the kidneys: blood flows to the kidneys through the renal artery. Convoluted tubule (a highly coiled portion of the nephron), descending and ascending limb of the loop of henle, distal convoluted. Processes along the nephron: each section of the nephron has different functions. These functions can be broken into filtration, Important terms: excretion = filtration + secretion reabsorption. Special epithelial cells called podocytes surround the capillaries. The podocytes have large filtration slits that are formed between pedicles: these structural features increase filtration at the glomerulus. Glomerular filtration starling forces. Starling forces cause the bulk of movement of fluid across capillaries due to a combination of hydrostatic and colloid osmotic forces.
