Where baby develops

11

Function of cervix

3

32

What happens in the first stage of birth?

The muscles of the womb contract (labour), amniotic sac bursts (waters break), contractions get stronger and the cervix dilates (up to 10 cm)

33

What happens in stage two of birth?

The baby is pushed out of the vagina head first, the umbilical cord is clamped and cut

34

What happens in stage three of birth?

The contractions continue for 10 mins approx and then the after birth (plancenta) is expelled

35

Define puberty

The sex organs fully mature and the body is capable of reproduction

36

Changes in boys during puberty

Rapid growth spurt, deepening of voice, body hair growth, penis and testes grow, produces sperm

37

Changes in girls during puberty

Growth spurt, body hair grows, pelvis/breasts/vagina/uterus grow, starts to produce eggs
