PATHOLOGY

Detailed explanation-1: -The bladder is a subperitoneal, hollow muscular organ that acts as a reservoir for urine.

Detailed explanation-2: -The urinary tract includes two sets of muscles that work together as a sphincter, closing off the urethra to keep urine in the bladder between your trips to the bathroom. The internal sphincter muscles of the bladder neck and urethra stay closed until your brain sends signals to urinate.

Detailed explanation-3: -The bladder is a sac-like organ in the pelvis that stores the urine produced by the kidneys. There are two tubular structures called ureters (one from each kidney) that drain the urine into the bladder. The urethra is the outflow tract of the bladder and connects the bladder to the exterior.
