muscle

Answer to Question 2

Mother and embryo have separate circulatory systems. The pancake-shaped placenta contains a membrane that acts as a filter that permits oxygen and nutrients to reach the embryo from the mother, and permits carbon dioxide and waste products to pass to the mother from the embryo. The mother then eliminates them through her lungs and kidneys. Germs that cause syphilis and German measles and drugs like aspirin, narcotics, alcohol and tranquilizers, can cross the placenta and affect the fetus.
