Renal corpuscle
Renal Corpuscle
The Renal Corpuscle (pronounced: /ˈriːnəl ˈkɔːrpʌsəl/) is a crucial part of the nephron, the basic functional unit of the kidney. It is responsible for the initial filtration of blood to form urine.
Etymology
The term "Renal Corpuscle" is derived from the Latin words 'renes' meaning kidney, and 'corpusculum' meaning little body.
Structure
The Renal Corpuscle is composed of two main structures: the Glomerulus and the Bowman's Capsule. The Glomerulus is a network of capillaries that performs the first step in filtering blood. The Bowman's Capsule is a cup-like sac that surrounds the Glomerulus and collects the filtrate that is produced.
Function
The primary function of the Renal Corpuscle is to filter blood. Blood enters the Glomerulus under high pressure, causing water, glucose, salts, and other small molecules to be forced out of the blood and into the Bowman's Capsule. This filtrate then moves on to the rest of the nephron, where it is further processed to form urine.
