Urinary System (Human): Components Structure The urinary system comprises: a kidneys, two bean-shaped organs 4 in long and 2–3 in wide; b ureters, two tubes 10 in long ; c bladder, a muscular organ; and d urethra, a tube 1.5 in long in women and 7–8 in long in men. Male Female a kidneys a kidneys b ureters b ureters c bladder c bladder d urethra d urethra Functions The urinary system is one of the methods by which the body eliminates toxins and wastes produced during metabolism. These methods are: 1 breathing out the gas carbon dioxide (respiratory system); 2 excreting water, salts, and urea (an end product of protein) through the skin; 3 excreting bile salts, cellulose, bacteria, and fibrous waste in feces (digestive system); and 4 excreting wastes in urine (urinary system). The urinary system: ● filters blood; ● removes wastes; and ● flushes wastes out through the urine. Other functions of the system include: ● maintaining the balance of water and salt in the body; and ● regulating the acid balance of the blood. © Diagram Visual Information Ltd. The functions of each organ in the system are described below. Kidneys Filter blood, removing wastes, excess water, and salts; ● secrete hormones renin and erythropoietin; and ● activate vitamin D. ● Ureters ● Take urine from kidneys to the bladder. Bladder ● Collects urine. Urethra ● Eliminates urine from the bladder; and ● in men, serves as passage for sperm during ejaculation.
