3. Reproduction
• Primary sexual characteristics
The reproductive systems
• Secondary sexual characteristics:
-girls develop breasts and their hips get wider
-Boys get deeper voices
4. REPRODUCTIVE CELL
Sperm are the male reproductive cell.
They are smalls. They have a head and a long
tail called flagellum. They are produced in
large numbers from the time of puberty.
ova are the female reproductive cell.
They do not move .From puberty, an ovum
matures every month.
5. THE REPRODUCTIVE SYSTEM
The reproductive system is made up of these
organs:
• The ovaries produce ova
• The utherus is where the baby develops
• The fallopian tubes connect the ovaries to the
uterus
• The vagina connects the uterus to the outside of
the body.
• The vulva is the external part of the female
reproductive system.
6. THE MALE REPRODUCTIVE SYSTEM
The male reproductive system is made up of
these organs.
• The testicles are outside the body. They produce
sperm. They are covered by a bag of skin called the
scrotum.
• The vas deferens take sperm from the testicles to the
urethra.
• The urethra takes sperm outside the body.
• The seminal vesicles and prostate produce seminal
fluide and send it to the urethra.
• The penis is outside the male reproductive system.
8. PREGNANCY
• The placenta takes nutrients and oxygen from the
mother’s blood to the embryo.
• The umbilical cord connects the embryo to the
placenta.
• The amniotic sac protects the embryo.
The baby develope step by step.
• After 3 months: the embryo has all its organs. It
becomes a foetus.
• After 5 months: the baby’s body develops and it
starts moving and the mother feels it.
• After 9 months: the baby is ready to be born and
it weighs around 3 kg
9. LABOUR
The process of giving birth is called labour. Labour
takes place in three phases:
• Dilation rhythmic contractions make the opening
of the vagina and vulva big enogh for the baby to
come out.
• Expulsion: the baby is born and the doctor cuts
the umbilical cord.
• Aftherbirth: the placenta comes out of the
mother’s body.
