Introduction
The urinary system, also known as the renal system, is a fundamental component of the human body responsible for regulating the composition and volume of bodily fluids. At its core are the kidneys, which act as natural filtration units, removing waste products, excess substances, and toxins from the bloodstream to produce urine.
This urine is then transported through the ureters to the urinary bladder, where it is temporarily stored. When the bladder is full, the urine is expelled from the body through the urethra. In addition to waste elimination, the urinary system plays a crucial role in maintaining proper water and electrolyte balance, regulating blood pressure, controlling blood pH, and managing the concentration of ions, all of which are essential for overall health and homeostasis.
Function of the Urinary System:
