1. Renal corpuscle: This is the filtering unit of the nephron, where blood is filtered. It consists of two components:

* Glomerulus: A network of capillaries where filtration occurs.

* Bowman's capsule: A cup-like structure that surrounds the glomerulus and collects the filtered fluid.

2. Renal tubule: This is the long, twisting tube where the filtered fluid is processed and modified. It consists of several segments:

* Proximal convoluted tubule (PCT): Reabsorption of most water, nutrients, and electrolytes.

* Loop of Henle: Reabsorption of water and ions, creating a concentration gradient in the medulla.

* Distal convoluted tubule (DCT): Reabsorption of water and electrolytes under hormonal control.

* Collecting duct: Final adjustment of water and electrolyte balance, leading to urine formation.
