The bladder is a hollow, muscular organ located in the lower abdomen, specifically in the pelvic cavity. It sits just behind the pubic bone (pubic symphysis) and is held in place by ligaments attached to the pelvic bones and surrounding organs
. In males, the bladder is positioned between the pubic bone in front and the rectum behind
. In females, it is located in front of the vagina and uterus
. When empty, the bladder lies within the lesser pelvis; when full, it can expand upward into the abdominal cavity
. It rests on the pelvic floor muscles, which support it from below
. Thus, the bladder is situated centrally in the lower pelvis, with its exact position varying slightly depending on sex and bladder fullness.
