In which region of the kidney are the renal pyramids located?
Solution
Correct Answer: Option B
The renal pyramids are located in the medulla of the kidney. The kidney is composed of two main regions: the outer cortex and the inner medulla. The renal pyramids appear as cone-shaped structures within the medulla and are responsible for the transport of urine from the outer part of the kidney, the cortex, where filtration occurs, to the renal pelvis, where urine collects before moving to the ureter.
Each pyramid contains numerous nephrons’ loops of Henle and collecting ducts, which play crucial roles in urine formation and concentration. The renal pelvis is a funnel-shaped cavity that collects urine from the renal pyramids, and the hilum is the entry and exit site for renal vessels, nerves, and the ureter.
Therefore, the correct answer is Medulla.
