PATHOLOGY

Detailed explanation-1: -The mature renal medulla, the inner part of the kidney, consists of the medullary collecting ducts, loops of Henle, vasa recta and the interstitium.

Detailed explanation-2: -Henle’s loop dips down from the cortex of the kidney into the deeper tissues of the medulla before looping back up into the cortex. Here, the tubule once again becomes convoluted, forming the distal tubule. The distal tubule ultimately dips back into the medulla, where it connects with a collecting tubule.

Detailed explanation-3: -Medullary collecting duct The inner segment is the part of the collecting duct system between the outer segment and the papillary ducts.
