The human urinary system is a complex network responsible for the production, storage, and excretion of urine, which helps maintain homeostasis by regulating water, electrolytes, and waste products in the body. It consists of two kidneys, which filter blood to produce urine, two ureters that transport urine from the kidneys to the bladder, a bladder that stores urine, and a urethra through which urine is expelled from the body. The kidneys contain functional units called nephrons, which play a crucial role in filtering blood and reabsorbing essential substances while excreting waste products. Hormonal regulation, particularly by antidiuretic hormone (ADH) and aldosterone, further influences the concentration and volume of urine produced, adapting to the body's hydration needs
