2.69 Urinary system

In the urinary system 

•  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.
