Test: Regulation of Kidney Function (NCERT) - Question 3

Which of the following sequences is correct?

Detailed Solution for Test: Regulation of Kidney Function (NCERT) - Question 3

An increase in body fluid volume can switch off the osmoreceptors present in the body which further suppresses  the release of ADH from neurohypophysis. ADH affects the Kidney function by its constricting effects on blood vessels. This will increase the blood pressure and an increase in blood pressure will increase the glomerular blood flow and thereby the GFR. A fall in GFR activates the JG cells to release renin which converts angiotensinogen in blood to angiotensin I which is further convert to angiotensin II. Angiotensin II stimulates the  adrenal cortex to release aldesterone.

Test: Regulation of Kidney Function (NCERT) - Question 4

Which one of the following statements is correct with respect to kidney function regulation?

Detailed Solution for Test: Regulation of Kidney Function (NCERT) - Question 4
