The urinary bladder collects a waste product of the metabolism known as urine, which is released by the kidneys during purification of the blood; the ureters connect the kidneys (and urine) to the bladder, and stored urine is released from the body via the urethra during the process of urination.
The bladder rests on floor of the pelvic bone and is both hollow and elastic as a means of accommodating urine build-up. However, the exact location of the bladder differs in males and females.
More specifically, in males, the bladder rests between the pubic symphysis and the rectum, which is the end portion of the excretory system and the intestines; it is also positioned above the prostate and the rectovesical excavation creates a thin wall between the rectum and the bladder. In females, the bladder rests below the uterus and above the vaginal canal.
Additionally, the amount of urine the bladder can contain is greater in males than in females. In infants, and very young children, the bladder is actually located in the abdomen and then grows into the lower abdomen with age.
