Urinary system, illustration. The two kidneys are at centre left and centre right. They are supplied with blood by arteries branching off from the aorta (red, centre). Blood leaves the kidneys via the renal veins, which drain into the vena cava (blue, centre). The kidneys clean the blood, removing urea which is excreted as urine. The urine flows down the ureters (white tubes) to the bladder (bottom centre) before being removed from the body during urination. This is a male body, with the prostate gland shown at the base of the bladder. | |
