Question:
Detail the structure and function of the glomerulus within a nephron.
Answer:
The glomerulus is a cluster of capillaries found within Bowman’s capsule of a nephron. It is specialized for high-pressure filtration, serving as the initial step in urine formation. The glomerular capillaries have a high-pressure environment that forces small molecules and water out of the bloodstream into Bowman’s capsule. This process is facilitated by fenestrated (porous) capillary walls and the presence of podocytes in Bowman’s capsule, which have foot-like extensions.
