A)
Fetus drives its nutrition from mother through placenta which is the outer layer of the cells called as trophoblast while inner layer of the cells forms fetus which is known as embryoblast. Once placenta is formed nutrients, oxygen and waste products start transferring between mother to fetus. Placenta is cylindrical tube like structure.
B)
Waste removal takes place by placenta which also carries nutrients for fetus.
C)
Birth takes place after 280 days or about 40 weeks and this whole birth cycle completes and there is a regular and painful muscle contraction and dilation of the neck of the womb after this birth takes place.
