The document summarizes the process of human reproduction in females and males. It describes how sperm and eggs are produced and their anatomy. It explains conception, fertilization, and implantation. It then outlines fetal development, including the formation of the placenta and amniotic sac. It provides diagrams of the female reproductive system and the journey of sperm. It also briefly mentions the formation of monozygotic twins from a single fertilized egg splitting.

The Process of
Reproduction

4. The male reproductive cell is called the sperm
The female reproductive cell is called the egg

5. Millions of sperms are produced a day after a
male hits puberty
Eggs are formed at the time of birth and are
lost every month after puberty

6. The sperms are the only cells that move,
that is why they have tails
The tail gives the sperm cell movement

7. Sperm Anatomy
Nucleus
Head Tail
The size is about 0.05 mm

8. Egg Anatomy
Nucleus
Cytoplasm
Jelly Layer
The size is 0.10 mm

9. When the sperm and egg join it is called conception
The fusion of the female nucleus with the male
nucleus is called fertilization
Implantation is when the mass of cells is settled into
cells is settled into the wall of the uterus

10. Female Reproductive System
Anatomy
Fallopian Tubes
Ovaries
Cervix
Uterus
Vagina
Ovaries

11. Sperm form in the testes
Sperms get pumped out along the sperm ducts during sex
They pass glands which add fluids to help the sperm stay alive.
Then the mixture of sperm and fluid — called semen —spurts out
through his penis

12. A fetus forms when cells start to specialize and produce
different tissues and organs
The placenta is a muscular lining between the mother and the
fetus that gives the fetus oxygen and nutrients
When the fetus is settled in the uterus, some of the cells make
contact with the mother's blood supply
They began to form a placenta and umbilical cord to pass
nutrients and oxygen from her blood to the fetus

13. The placenta does the job of the small intestines and
lungs
The blood vessels in the placenta have a large
surface area, so that nutrients and oxygen can
diffuse into them quickly
Waste molecules like carbon dioxide and urea
diffuse from the fetus to the mother

14. There is a sack around the baby called the
amniotic membrane/ sack
It is filled with a liquid called the amniotic fluid
The fluid protects the fetus from bumps and
lets it move

Monozygotic Twins (MZTs)

16. It all starts when a man and
woman have sex

17. The sperm journey starts with insemination (the
introduction of sperm into a female’s reproductive
system)

18. The sperm journey starts with insemination (the
introduction of sperm into a female’s reproductive
system)

19. The sperm journey starts with insemination (the
introduction of sperm into a female’s reproductive
system)

20. The sperm releases enzymes that melt the egg’s outer layer

21. Fertilization

22. The fertilized egg splits into two, to make twins

23. The zygotes turn into blastocytes

24. Embryos

25. Fetuses

26. Two Baby Boys are born!
