Manitoba Nephrology Nurse Practice Test

Where does glomerular filtrate collect after filtration?

1. Proximal convoluted tubule

2. Distal convoluted tubule

3. Bowman's capsule

4. Loop of Henle

The correct answer is: Bowman's capsule

Glomerular filtrate collects in Bowman's capsule after passing through the capillary walls of the glomerulus. This process is the first step in urine formation. Bowman's capsule is a cup-like structure that surrounds glomeruli in the nephron and serves as the site where the filtered fluid, which contains water, ions, and small molecules, is gathered before moving into the renal tubules. Once the filtrate is formed in Bowman's capsule, it flows into the proximal convoluted tubule, where further processing takes place. Understanding this pathway is essential for grasping how the kidneys filter blood and produce urine.
