(iii) Fallopian tube: It passes down the ovum towards the uterus released by
the ovary.

 It contains villi on the embryo side. The mother’s end of the placenta has
blood spaces which surround the villi.

blood.
 The foetus gives away waste products and carbon dioxide to the mother’s
blood for excretion.
