Here and in the final portions of the DCT, there are cells that respond to the hormones aldosterone and antidiuretic hormone (ADH), and there are cells that secrete H + in an effort to maintain proper pH. Various collecting ducts within the medullary pyramids merge to form papillary ducts, which drain eventually into the renal pelvis through the medullary papillae. Urine collects in the renal pelvis and drains out of the kidney through the ureter. The efferent arteriole carries blood away from the glomerular capillaries to form peritubular capillaries. These capillaries weave around the portions of the renal tubule that lie in the renal cortex. In portions of the nephron loop that descend deep into the renal medulla, the capillaries form loops, called vasa recta, that cross between the ascending and descending limbs. The peritubular called vasa recta, that cross between the ascending and descending limbs....
