2.69 Urinary system

Describe the structure of the urinary system, includin the kidneys, uterus, bladder and urethra.

In the urinary system we have two kidneys the right and the left each with its own blood supply carrying out the process of filtration, osmoregulation, and excretion. From each kidney there is a tube leading to the bladder which is called the ureter. The urine stored in the bladder travels to outside through the urethra and down through the vagina or the penis.
