Question

Which is not a part of renal pyramid:
$\left( A \right)$ Collecting Ducts
$\left( B \right)$ Loop of Henle
$\left( C \right)$ Convoluted tubules
$\left( D \right)$ Peritubular capillaries

Answer 1

Hint: The renal medulla is the innermost part of the kidney.

Complete step-by-step answer:
Renal pyramids are the conical areas of medulla. Peritubular capillaries, collecting ducts and Loop of Henle lie in the renal pyramids while convoluted tubules lie in the cortex of the kidney.
Renal pyramid, any of the triangular sections of tissue that constitute the medulla, or inner substance, of the kidney. The pyramids consist mainly of tubules that transport urine from the cortical, or outer, part of the kidney, where urine is produced, to the calyces, or cup-shaped cavities in which urine collects before it passes through the ureter to the bladder.
Hence, the correct option is $\left( C \right)$.

Note: The medulla is divided into a few conical masses called medullary pyramids projecting into the calyces. The cortex extends in between the medullary pyramids as renal columns called Columns of Bertani.
