Question

Mention the pathway of urine in our body starting from the organ of its formation to its excretion.

Answer 1

Urine production begins in the kidneys. Here is the sequential pathway:

1. Kidneys: The kidneys produce urine by filtering blood and removing waste through many nephrons.
2. Renal Tubules: Urine is formed in the nephrons through filtration, reabsorption, and secretion in renal tubules.
3. Renal Pelvis: Urine gathers in the renal pelvis, a reservoir-like region in the kidney.
4. Ureters: Peristaltic contractions drive urine through the muscular ureters that connect the kidneys and bladder.
5. Urinary Bladder: Urine is temporarily stored in the bladder, a muscular organ that expands as it fills.
6. Urethra: The urethra transports urine from the bladder to the body's exterior during urination.
