Verified step by step guidance
1
Begin by understanding the anatomy of the kidney, which is divided into two main regions: the renal cortex and the renal medulla.
The renal medulla is the innermost part of the kidney and contains structures such as the renal pyramids, collecting ducts, and the Loop of Henle.
The renal corpuscle, however, is part of the nephron located in the renal cortex, not the medulla. It consists of the glomerulus and Bowman's capsule, where filtration of blood begins.
Review the function of each structure: Collecting ducts are involved in the final concentration of urine, renal pyramids contain the loops of Henle and collecting ducts, and the Loop of Henle is crucial for the concentration gradient in the medulla.
Conclude that the renal corpuscle is not found in the renal medulla, as it is located in the renal cortex, distinguishing it from the other structures listed.
