Quizplus · Accepted Answer

The urinary bladder is derived from the allantois, which is an extraembryonic membrane that becomes part of the umbilical cord and later forms part of the bladder and urethra. The yolk sac contributes to the formation of the digestive system, the amnion is a membrane that surrounds the embryo, the chorion forms the outermost membrane that surrounds the embryo and contributes to the placenta, and the decidua is part of the uterine lining during pregnancy.
