Verified step by step guidance

Begin by identifying the main regions of the kidney: the renal cortex, renal medulla, and renal pelvis.

Understand that the renal medulla is the innermost part of the kidney, characterized by its darker, reddish-brown appearance.

Recognize that the renal medulla contains cone-shaped tissue masses known as renal pyramids, which are crucial for the kidney's function in filtering blood and producing urine.

Differentiate between the renal medulla and other parts of the kidney, such as the renal cortex, which is the outer layer, and the renal pelvis, which is the funnel-shaped structure that collects urine.

Conclude that the renal medulla is the correct term for the darker, reddish-brown area of the kidney with renal pyramids, as opposed to the renal cortex or renal pelvis.
