Question

Which one of the following is present in the renal pyramid

• A. Peritubular capillary
• B. Convoluted tubules
• C. Collecting ducts
• D. Both A and C

Answer 1

The correct option is D Both A and C

The renal pyramid is the triangular shape medullary tissue in the kidney.

Medulla of kidney contains a loop of Henley, collecting tubes while the glomerulus and convoluted tubules (PCT, DCT) are situated in the cortex.

Peritubular capillaries are the network of blood vessels around the loop of Henley. As loop of Henley is in renal pyramid peritubular capillaries are also present in renal pyramid

So the only peritubular capillaries and collecting ducts are present in the renal pyramid but not the convoluted tubules.
