How urine produce and eliminate?

Urine is produced in the kidneys through a process called filtration, where blood is filtered to remove waste products, excess salts, and water. This filtered fluid then undergoes reabsorption and secretion in the nephron, leading to the formation of urine. Once formed, urine is transported to the bladder via the ureters and stored until it is eliminated from the body through the urethra during urination. This process helps regulate the body's fluid balance and removes toxins.
