Ovary: It produces female gametes. One ovum is released by one ovary
every month. It also secretes hormones oestrogen and progesterone.
(ii) Uterus: It protects and nourishes the developing embryo.
(iii) Fallopian tube: It passes down the ovum towards the uterus released by
the ovary.
Structure of the placenta in human female:
 The placenta is a disc which is embedded in the uterine wall.
 It contains villi on the embryo side. The mother’s end of the placenta has
blood spaces which surround the villi.
Functions of the placenta in human female:
 Nutrients and oxygen are received by the foetus from the mother’s
blood.
 The foetus gives away waste products and carbon dioxide to the mother’s
blood for excretion.
