The sequence of events in the uterus of a human female from
fertilization of egg till childbirth.
Explanation:
- After the menstruation period, ovaries present in the female reproductive system releases a mature egg that lives for only 12-24 hours.
- If during this period, sperm collected through males enters into the cervix of females, there are high chances of fertilization of a mature egg.
- Once the egg gets fertilized, it implanted into the uterus during seven days of the period.
- During the whole gestation period of human fertilization, human beta chorionic gonadotropin (β-HCG) hormone level rises and decrease.
- This human beta chorionic gonadotropin (β-HCG) helps in the development of the embryo.
- After the implantation of the embryo into the uterus, endometrium lining helps in the excretion of waste material for four trimesters.
- Upcoming trimesters had the placenta as a way to feed the embryo and excretion process that continues till the birth of a child.
