Question

Quizplus · Accepted Answer

The urinary bladder's primary function is to store urine until it is expelled from the body during urination. The ureters transport urine from the kidneys to the bladder, not from the bladder to the exterior. The trigone is a smooth triangular area inside the bladder, but it is not a muscle; it's defined by the openings of the ureters and the urethra. The bladder is located in the pelvic cavity, inferior to the kidneys, and it does not filter urine; that function is performed by the kidneys.
