The embryo development

When a woman becomes pregnant her menstruation disappears until after the baby is born. Pregnancy lasts about 9 months and ends in the labour.

During the first stages of the pregnancy the embryo develops. Besides, different structures are created to protect and provide foods to him. These structures are:

• The placenta. It is inside the womb, where the implantation happens. The placenta takes nutrients and oxygen from the mother’s blood to the embryo.

• The umbilical cord. It is made up of blood vessels that connect the embryo to the placenta.

• The amniotic sac. It is a fluid filled sac that protects the embryo.

Fetal developmentDuring the first stages of the pregnancy the organs of

the future baby are formed and during the last stages the fetus grows.

• After three months the embryo has all its organs. From now it is called fetus.

• After 5 months the mother can feel the fetus movement and it is possible to know the sex of the baby by ultrasound.

• After 9 months the baby is ready to be born. It weighs around 3 kilos and measures around 50 cm. Preemies are born before 9 months and they need special cares.

The process of conception and embryonic development

The fetus feeding and health depend on his mother’s. It is very important that mothers have healthy habits during the pregnancy.

Labour

Labour is the process of giving birth. It usually happens after nine months of pregnancy.The placenta and the umbilical cord leaves with the baby.

Labour takes places in three phases:• Dilation: the womb begins to dilate for the

baby to come out by means of rhythmic contractions.

• Expulsion: the baby is born through the vagina, which also dilates. The umbilical cord is cut and its scar is the navel.

• After birth: the placenta comes out of the mother’s body.

If there is a problem, a cesarean is performed, which is a medical surgery to take the baby out of the mother’s belly.
