Explanation: First of all, the placenta forms and develops during pregnancy, attaches to the wall of the uterus and its primary function is to nourish and provide oxygen to the baby that develops and grows in the uterus. In addition, the placenta removes all waste matter and carbon dioxide from the fetus.
