The urinary system, which is primarily concerned with the removal of nitrogenous waste products from the body.
The kidneys function in several capacities: as an excretory organ, maintaining electrolyte continuity, stabilizing the acid-base balance, and maintaining an adequate fluid balance. The urinary system consists of two kidneys, two ureters, a bladder, and a urethra. As the kidneys filter toxins from the blood, these toxins are deposited out of the body in urine; at the same time the kidneys are retaining those substances that help maintain a state of homeostasis within the body.
The formation of urine by the kidneys involves several steps: filtration, reabsorption, and secretion. The malfunction of the kidneys can alter one’s state of wellness drastically, and if untreated can cause irreversible damage to the kidneys and even death
