Expert Answer:

  1. Gametogenesis: Gametogenesis is a process by which diploid cells undergo cell division and differentiation to form mature haploid gametes. 
  2. Spermatogenesis: Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.
  3. Oogenesis: Oogenesis is the process by which haploid ova or eggs develop from the primary oocyte in the ovaries. 
  4. Ovulation: Ovulation is when a mature egg is released from the ovary.
  5. Fertilization: Fertilisation is the fusion of sperm and egg to form a new organism of the same species.
  6. Implantation: Implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus.
  7. Embryogenesis: Embryogenesis refers to the development and formation of the human embryo through the process of cell division and cellular differentiation.
  8. Parturition: Parturition is the process of delivering the baby and placenta from the uterus to the vagina to the outside world.
  9. Pregnancy: Pregnancy is the time during which one or more offspring develops inside a woman.
