The nephron is the functional unit of the kidney, processing blood filtrate to maintain fluid balance and eliminate waste.
Nephron Segments
- Glomerulus: Filters blood based on molecular size and charge.
- Proximal Convoluted Tubule (PCT): Reabsorbs the majority of filtered water, sodium, glucose, and amino acids.
- Collecting Duct: Final site of water reabsorption regulated by Antidiuretic Hormone (ADH).
