1. What is the scientific name?Systema urinarium
2. What is the functional unit of kidney?Nephron
3. What is a nephron and why is it important?A nephron is a tiny filter inside each kidney that cleans blood and makes pee. Each kidney has about one million of them, and they do filtering, reabsorption, and secretion to keep the body healthy.
4. How does the body decide when to go to the bathroom?The bladder can hold up to 800 milliliters, but the urge starts when it has about 200-300 milliliters. The bladder muscle contracts and the sphincters relax to let pee out.

Glomerular Filtration: The initial process in the nephron where blood plasma is filtered from capillaries into Bowman's capsule.
Selective Reabsorption: The process by which useful substances are moved from the renal tubule back into the bloodstream.
Homeostasis: The maintenance of a stable internal environment within an organism, despite external changes.
