Question

Nephrons are of two types : cortical and juxtamedullary according to their relative position in the cortex Juxtamedullary nephrons have short loop of Henle while cortical nephrons have long loop of Henle

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

The Correct Option is C

On the basis of location, the nephrons are of two types. In majority of nephrons, the loop of Henle is too short and extends only little into the medulla. These nephrons are called cortical nephrons and form $85\%$ of the total nephrons. In some of the nephrons, the loop of Henle is very Ipng and runs deep into the medulla. These nephrons are called juxtamedullary nephrons and form $15\%$ of the total nephrons
