Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: The Stages of Pregnancy and Childbirth.

Level#1:

Pregnancy usually lasts about nine months. Pregnancy is often divided into three stages, or trimester. During each trimester, the embryo will grow in length and in weight. It will develop organs that it will need to survive outside of its mother's uterus. After about eight weeks, the embryo is called a fetus. The fetus grows in a pouch-like structure, called the amniotic sac.

1. How long does pregnancy usually last?




2. What are the three stages that pregnancy is divided into?




3. What happens to the embryo during each trimester?






Level#2:

Pregnancy usually lasts about nine months. Pregnancy is often divided into three stages, or trimester. During each trimester, the embryo will grow in length and in weight. It will develop organs that it will need to survive outside of its mother's uterus. After about eight weeks, the embryo is called a fetus. The fetus grows in a pouch-like structure, called the amniotic sac. Shortly before birth, the amniotic sac usually breaks. Strong muscle movements in the mother's uterus, or contractions, force the baby out of the mother's body. Contractions are also known as labor pains. The baby leaves its mother's body through the vagina.

The baby leaves its mother's body through the vagina. After the baby is born, the placenta is also pushed out of the mother's body. Shortly after birth the mother's breasts begin to produce milk. the result is from the effects of hormones from the pregnancy.

1. Explain how long pregnancy usually lasts, and what is happening to the embryo during each trimester.






2. Explain what the fetus grow in during its development and what happens shortly before birth.






3. Explain what contractions are and what they are also known as.
