Document Summary
712 - 727 (6th ed. p. 711 726) Describe how the plasma membrane of the dome cells allows them to change shape: describe the histological layers of the ureter and urinary bladder, differentiate between the ureter and urinary bladder in a light micrograph. Peritubular capillaries receive blood from the efferent arteriole; associated with convoluted tubules. Vasa recta capillaries branching off the peritubular capillaries; associated with loop of henle. Active transport to reabsorb nutrients, vitamins, amino acids, glucose, small proteins, cations. Cl and water follow: loop of henle. Thick segment of the descending limb has the similar structure and function as pct. Water passively diffuses into the interstitium to concentrate the urine due to the gradient created by reabsorption of na and cl in the ascending limb. Na and cl passively diffuse into the interstitium. Na is actively transported into the interstitium: dct. Antidiuretic hormone makes it more permeable to water: collecting/connecting tubule.
