The urinary bladder is a hollow, muscular and distensible organ that sits on the pelvic floor (superior to the prostate in males). On its anterior border lies the pubic symphysis and, on its posterior border, the vagina (in females) and rectum.
The ureters enter the bladder diagonally from its dorsolateral floor toward the midline.
A normal human bladder has a capacity of 400 to 500 ml.
The study of the function of the bladder is called urodynamics
