Best Answer

Ans.  Ovary-Ovaries are the primary  reproductive organs  in a woman  (or female). The function  of ovaries is to produce  mature  female sex cells called 'ova' or 'eggs'  and also to secrete the female sex hormones.

 Oviduct-The ovum (or egg cell) released by an ovary goes into the oviduct through its funnel shaped opening. The fertilisation of egg by a sperm takes place in the oviduct.

Uterus-The growth  and development of a fertilised. ovum  (or fertilised egg) into a baby takes place in the uterus.

After fertilisation,  zygote  is formed  which  develops  into  an  embryo.  The embryo  gets nutrition  from the mother's  blood with the help of a special tissue called placenta. This is a disc which is embedded  in the uterine wall. It contains finger-like projections called villi on the embryo's  side of the tissue. On the mother's side are blood spaces, which surround the villi. This provides large surface area for glucose and oxygen to pass from the mother to the embryo. In this way, the embryo  gets its nutrition
