- Renin
View Solution
7.
Which of the following factors is responsible for the formation of concentrated urine?

View Solution
10.
Which of the following factors is responsible for the formation of concentrated urine ?
- Secretion of erythropoietin by Juxtaglomerular complex
- Hydrostatic pressure during glomerular liltrntion.

- Maintaining hyperosmolarity towards inner medullary interstitium in the kidneys
View Solution
11.
Human urine is usually acidic because
- potassium and sodium exchange generates acidity
- hydrogen ions are actively secreted into the filtrate
- the sodium transporter exchanges one hydrogen ion for each sodium ion, in peritubular capillaries.
- excreted plasma proteins are acidic.

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Nephrons are of two types: Cortical & Juxta medullary, based on their relative position in cortex and medulla.

In the light of the above statements, choose the correct answer from the options given below:
- Both A and R are true but R is NOT the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
