Question

Quizplus · Accepted Answer

The fetal pulmonary trunk is connected to the fetal aorta via the ductus arteriosus, which is a blood vessel that shunts blood away from the lungs and towards the body before birth. After birth, the ductus arteriosus typically closes and becomes the ligamentum arteriosum. Therefore, option B is incorrect. Options C and D are not directly related to the connection between the fetal pulmonary trunk and aorta.
