Implantation, ovulation, child birth, gestation, fertilization.

Answer 1

Ovulation → fertilization → implantation → gestation → childbirth

Ovulation is the release of eggs from the ovaries. In humans, this event occurs when the ovarian follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm. Further, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is called a blastocyst. It is by this adhesion that the embryo receives oxygen and nutrients from the mother to be able to grow. This is followed by gestation, the average length of human gestation is 280 days, or 40 weeks, from the first day of the woman's last menstrual period.
