¿Por qué la orina es amarilla?

The video explains the process of urine production and its yellow color. Blood circulates waste to the kidneys, where it is filtered to form urine, primarily composed of water and urea. Urobilin, a byproduct of old blood cell recycling, gives urine its yellow hue. Urine travels from the kidneys to the bladder, which stores it until urination. The bladder's sphincter muscles control the release of urine through the urethra.
