Answer 1

Renal Cortex :It is the outer-most part of the kidney that contains glomeruli, Bowman's capsule and the proximal and distal convoluted tubules.

Renal medulla: It is the region just inner to renal cortex and contains loop of Henle and collecting duct.

Renal Cortex	Renal medulla
1. It is the outermost region towards the convex surface of the kidney.	1. It is the region just inner to renal cortex.
2. It contains glomerulus, Proximal Convoluted Tubule (PCT), Distal Convoluted tubule (DCT) and Bowman's capsule.	2. It contains loop of Henle and collecting ducts.
4. It filters blood.	4. It regulates water and salt concentration in the blood.
5. It appears dark and dotted due to the presence of Malpighian Corpuscles.	5. It is striped in appearance due to the presence of renal pyramids.
