The bladder is arguably one of the most important organs in the body. Without it, we could not eliminate liquid waste (urine). It is just one part of an intricate system of organs dedicated to conveying this waste out of the body and keeping us healthy. The bladder is complex -- it connects with several other organs, including the brain.
The bladder is a "storage organ." It is a sac of muscle that sits inside the pelvis. It lies just above and behind the pubic bone. The renal system, including the kidneys and urethra, connect to the bladder; together, these organs facilitate the removal of waste from the body. As one would expect, the bladder is hollow and can expand as more urine accumulates.
