Answer 1

Hint: Foetus develops inside the uterus of the mother. When the foetus becomes full term, parturition occurs and the newborn baby comes out. During the foetal life, several changes happen to foetus beginning from the first month to the end of the nine months.

Complete answer:
The gestational period is the time in which the embryo grows into a fully developed foetus inside the uterus of the mother. It lives there for almost nine months and then, parturition occurs. The fusion of male and female gametes occurs inside the fallopian tube to form a zygote. This zygote undergoes cleavage and becomes a multicellular mass of cells. Now, the structure is called a blastocyst. It is the blastocyst that gets implanted inside the uterine wall. There are varied changes happening to the foetus inside the uterine wall. Heart development is the first step and it happens in the first month itself. Limbs and digits are formed in the second month. At the end of three months, all the major organs are formed. The first movement of the foetus is perceived in the fifth month. It is at this period growth of hair happens in the head. Eyelids get separated and eyelashes are formed in the sixth month. At the end of nine months, development is complete and the foetus is ready for parturition.

Note: It is important to know that some foetus are delivered without completing the total gestational period. In some babies, foetal growth won’t take place in an efficient manner and it results in physical or mental retardation in the children.
