Answer 1

Glomerular filtration

1. Glomerular filtration is step one in urine formation. Glomerular blood is filtered through filtration slits found in Bowman's tablet.
2. The Bowman's tablet collects the filtrate and enters the tubules of the nephron. Glomerular filtration is likewise known as ultrafiltration due to the fact that filtrate is composed of virtually all parts of plasma besides proteins. Hence step one in urine formation is Ultrafiltration.

The first step in urine formation is the filtration of the blood, which is carried by the glomerulus and is called glomerular filtration.
