Document Summary

Structures of the urinary system: composed of the paired kidneys & accessory structures, accessory structure include the ureters, the urinary bladder & the urethra, site of urine formation, urine is produced in the kidneys, and then drains through the ureters to the urinary bladder, where the urine is stored, urine is eliminated from the body through the urethra. Functions of the kidneys: regulation of ecf volume & blood pressure, regulation of osmolarity, maintenance of ion balance, homeostatic regulation of ph, excretion of wastes, production of hormones. The nephron: the functional unit of the kidney modifies fluid volume & osmolarity, kidney has 2 layers formed by the nephrons, an outer cortex & inner medulla, 80% of nephrons are within the cortex, consists of a specialized tubular structure & closely associated blood vessels, one nephron has 2 arterioles and 2 sets of capillaries.
