Which of the following structures are situated in the cortical region of the kidney? I. Malpighian corpuscle II. PCT (Proximal Convoluted Tubule) III. DCT (Distal Convoluted Tubule) IV. Loop of Henle V. Collecting duct

Step-by-step solution

The DCTs of many nephrons open into a straight tube called collecting duct, many of which converge and open into the renal pelvis through medullary pyramids in the calyces. The Malpighian corpuscle, PCT and DCT of the nephron are situated in the cortical region of the kidney whereas the loop of Henle dips into the medulla. In the majority of nephrons, the loop of Henle is too short and extends only very little into the medulla.
