Verified step by step guidance

Understand the anatomy of the kidney: The kidney is divided into two main regions—the renal cortex (outer layer) and the renal medulla (inner layer). The renal medulla is primarily responsible for concentrating urine and contains specific structures.

Identify the structures within the renal medulla: The renal medulla is composed of renal pyramids, which are cone-shaped structures. These pyramids contain loops of Henle and collecting ducts, which are essential for urine concentration.

Differentiate the listed structures: Glomeruli and renal corpuscles are part of the renal cortex, not the medulla. The renal capsule is the outer covering of the kidney and does not contribute to the medulla's function.

Focus on the correct structure: Renal pyramids are the primary structures that make up the renal medulla. They play a key role in the kidney's filtration and concentration processes.

Conclude with the correct answer: Based on the anatomical organization of the kidney, the renal pyramids are the correct answer as they are the main structures within the renal medulla.
