PATHOLOGY

Detailed explanation-1: -The bladder is located in the lesser pelvis when empty and extends into the abdominal cavity when full. In children, the bladder is located in the abdomen and does not completely descend into the pelvis until puberty. The bladder is a distensible organ and is typically able to hold up to 500 milliliters of urine.

Detailed explanation-2: -The pelvic cavity is a bowl-like structure that sits below the abdominal cavity. The true pelvis, or lesser pelvis, lies below the pelvic brim (Figure 1). This landmark begins at the level of the sacral promontory posteriorly and the pubic symphysis anteriorly.

Detailed explanation-3: -The urinary bladder belongs in the lower left lower quadrant. This quadrant also includes the descending colon, ileum, and part of the sigmoid colon.

Detailed explanation-4: -The urinary bladder is found inferior to the peritoneum, sitting on the pelvic floor. In females its inferior surface lays on the pubic symphysis and the posterior wall is in contact with the vagina and uterus.
