All the following are true regarding blood supply to the kidney, except - 
Select and explain. 
A. Stellate veins drain superficial zone, B. It is a type of portal-circulation, C. The renal artery divides into five segmental arteries before entering the hilum, D. Its segmental arteries are end-arteries
C: The renal artery divides into five segmental arteries before entering the hilum
Answer: C: The renal artery divides into five segmental arteries before entering the hilum 
Explanation: Kidney has five independent vascular segments

Segmental arteries divide into lobar branches.
Area of kidney supplied by lobar artery → renal → includes 1-2 pyramids and the adjacent part of the cortex.
Branches of renal arteries are end arteries.
Renal blood passes through 2 sets of capillary plexus.


High-pressure bed (60 mmHg) of glomerular plexus for filtration.
Low-pressure bed (13mmHg) of peritubular plexus for selective reabsorption and nutrition.

These are connected by efferent glomerular arterioles which act as a renal portal system.
