- The Baby's Support System
- Uterus
- Baby's Home for 9 months
- Fertilised egg embeds itself into the uterus lining
- Size and shape of an upside down pear
- Expands to keep the baby secure and protected
- Placenta
- Develops the first 12 months of pregnancy
- One side of the placenta is connected to the uterus and the other side to the foetus via the umbilical cord
- Produces hormones that maintain pregnancy
- A barrier against harmful substances
- Allows the foetus to eat, breathe and dispose of waste products
- Links the blood supply of the mother to the baby (although it never mixes)
- Pass antibodies from the mother to give some resistance to infections
- Umbilical Cord
- The baby's lifeline
- Connects the baby to the placenta
- Carries blood and nutrients to the baby and removes the waste products
- Immediately after birth it is clamped and cut
- Amniotic sac
- The amniotic sac is inside the uterus
- It contains the developing embryo/foetus
- The main purpose is to make sure the baby grows safely
- Amniotic fluid
- This is the warm fluid contained inside the amniotic sac
- If there is too much or too little fluid the baby will not continue growing
- The fluid enables the baby to float freely and allow limbs to stretch in early pregnancy
- The fluid keeps the baby at a constant temperature of 37 degrees C
- Supports and protects the baby from knocks just like a cushion
- The cervix
- The 'neck' of the uterus (womb)
- During labour the cervix dilates to allow the baby to pass through
- Cervical mucus
- Blocks the cervix to protect the uterus from infection
- During labour the mucus comes away
- Uterus
