Assertion : The amount of the filtrate formed by the kidneys per minute is called $\text{GFR}$.
Reason : $\text{GFR}$ in a healthy individual is approximately $25\ ml/\text{minute}$.

$ii$. Diameter of afferent arteriole is greater than that of efferent arteriole.
$iii$. Glomerular filtrate is deproteinised plasma and is acidic in nature.
$iv$. $PCT$ cells reabsorb low threshold substances like sulphates,nitrates actively against concentration gradient.
