The bladder is a small, flexible organ in the body that stores urine, which is produced by the kidneys. It is located in the lower abdomen and can expand as it fills with urine. When the bladder is full, it sends signals to the brain, indicating that it’s time to go to the bathroom. Urine is a waste product that helps remove excess water and toxins from the body. The bladder works with other parts of the urinary system, including the kidneys and urethra, to ensure that this process runs smoothly. Keeping the bladder healthy is important for overall well-being.
