Term. Describe the structural and functional relationships between the nephron tubules and their associated blood vessels. Definition. Portions of the nephron that extend from the renal corpuscle to the collecting duct allow exchange between the tubule and the peritubular capillaries.The epithelial cells in different segments are structurally different. For example, the membranes have different permeabilities and contain different transporters.ortions of the nephron that extend from the renal corpuscle to the collecting duct allow exchange between the tubule and the peritubular capillaries.

Kidney Health Care-David Mangusan Jr, PTRP. The nephron is the tiny filtering structure in your kidneys. Each of your kidneys contain more than a million tiny filtering nephrons that help clean your blood.Function of the Nephrons.Your nephrons help: Each nephron is composed of two main structures: the glomerulus and renal (kidney) tubule.The Glomerulus. The glomerulus is a tiny blood vessel or capillary, which looks like a ball of yarn.
