Urinary System
The urinary system, also known as the renal system, is a vital part of the human body responsible for the removal of waste products and excess substances through the production and excretion of urine. This system consists of two kidneys, two ureters, the bladder, and the urethra. The kidneys, located on either side of the spinal column just below the rib cage, are the central organs of this system. They filter the blood to remove waste products and extra water, which become urine. The kidneys also perform other crucial functions such as regulating blood pressure, electrolyte balance, and red blood cell production.
Urine flows from the kidneys through the ureters to the bladder, which acts as a storage reservoir. When the bladder reaches its storage limit, the body senses the need to urinate, and urine is expelled from the body through the urethra. The urinary system works closely with the lungs, skin, and intestines to maintain the body's electrolyte and acid-base balance, and with the endocrine system to manage blood pressure and volume. Proper functioning of the urinary system is essential for overall health, and disorders or diseases within this system can lead to significant medical conditions requiring prompt attention.
