Illustration of the female urinary system. The two kidneys are at upper center. The kidneys filter waste products from the blood. The waste products are transported as urine to the bladder (round, bottom) via the ureters (pink tubes). Urine is stored in the bladder until it exits the body via the urethra (bottom center). Also seen are the aorta (red, down center), the bodys main artery and the vena cava (blue, down center), the bodys main vein.
