Blood vessel leading to glomerulus is called
1 renal artery
2 efferent arteriole
3 renal vein
4 afferent arteriole
Explanation:
(d) Glomerulus is a tuft of capillaries formed by afferent arteriole (a fine branch of renal artery).

Which one of the following is not a part of a renal pyramid ?
1 Loop of Henle
2 Peritubular capillaries
3 Convoluted tubules
4 Collecting ducts
Explanation:
(c) Convoluted tubules is not a part of renal pyramid but a portion of the nephron in the kidney that functions in concentrating urine and in maintaining salt, water, and sugar balance. Renal pyramids (also called malpighian 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. The point of each pyramid, called the papilla, projects into a calyx.

Columns of Bertini in the kidneys of mammals are formed as extensions of
1 Cortex into medulla
2 Cortex into pelvis
3 Medulla into pelvis
4 Pelvis into ureter
Explanation:
(a) The renal column (or column of Bertini) is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.
