2. Notes:
Pregnancy begins when an egg cell is fertilized by a sperm cell.
When a woman becomes pregnant, her monthly menstrual period stops.
During pregnancy, the fertilized egg divides again and again, growing rapidly.
There are different stages of an embryo and then a fetus inside the mother’s womb.

3. 5. The embryo is the first stage and lasts eight weeks.
6. The next stage is the fetus. A fetus grows legs and arms, as well as internal organs like the heart.
7. Pregnancy usually lasts 40 weeks and is divided into three trimesters (periods of about 12 weeks).
8. The fetus lies in a bag of fluid called the amniotic sac.

4. 9. The mother’s blood passes food and oxygen to the fetus through the placenta, also known as the afterbirth.
10. The umbilical cord runs from the placenta and fetus, carrying blood between them.
11. During pregnancy, a woman gains 30% more blood and her heart rate goes up.
12. A woman’s breasts grow and develop milk glands to produce milk for feeding the baby.
