Question

Why does the medulla of the kidney show a striped appearance.​

Answer 1

Explanation:

The renal medulla is the innermost part of the kidney.

The renal medulla contains the structures of the nephrons responsible for maintaining the salt and water balance of the blood.

Though the renal medulla only receives a small percentage of the renal blood flow, the oxygen extraction is very high, causing a low oxygen tension and more importantly, a critical sensitivity to hypotension, hypoxia, and blood flow.

The medulla consists of a number of medullary pyramids, named because of their triangular shape. These are striped in appearance because they contain microscopic coiled tubes called nephrons, the functional unit of the kidney . ... This acts like a funnel draining the urine out of the kidney into the ureter.

Hope it will help

Thanks
