Document Summary
The urinary system contributes to homeostasis by altering blood composition, ph, volume, and pressure ; maintaining blood osmolarity; excreting wastes and foreign substances, and producing hormones. Major structures of the urinary system includes: the kidneys, the ureters, the urinary bladder, and a urethra. The kidneys filter blood plasma and then return most of the water and solutes to the bloodstream. The remaining blood solutes and water is what constitutes urine (1-2 l) The kidneys are the major structures of the urinary system. Regulation of ph: urine excretes a high level of h+ ions and conserve hco3- which is an important buffer to h+ -- this prevents acidosis in the blood. Functions include: regulation of blood ionic composition this deals with regulating blood levels of several ions such as. Sodium ions, potassium ions, and even calcium ions, chloride ions, and phosphate ions.
