The first step in urine formation is

An adult human excretes,on an average, . . . . . . litres of urine per day.

In a healthy individual, the Glomerular Filtration Rate $(GFR)$ is . . . . . . .

High blood pressure is maintained in the glomeruli compared to other capillaries because:

Study the following statements and select the correct answer from the given options.
$i$. Diameter of afferent arteriole being smaller raises glomerular pressure for ultrafiltration.
$ii$. The colloidal osmotic pressure of blood is about $30 \ mmHg$ that opposes ultrafiltration.
$iii$. The arrangement of podocytes favours ultrafiltration.
