Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: Pregnancy and Childbirth.
Level#1: When a man and a woman are both sexually mature, they can reproduce, or have a baby. They do so through sexual intercourse. During intercourse, a man inserts his penis into a woman's vagina and releases sperm. Once released into a female's vagina, sperm cells travel through the cervix and into the uterus. Then, they travel into the fallopian tubes. Fertilization, or the joining of the sperm and egg, usually happens in one of the fallopian tubes. Once the sperm and egg cells have united, a woman becomes pregnant.
1. Where do sperm cells go after they are released into a woman's vagina?
2 Where do sperm travel to after they leave the uterus?
3. Where does fertilization usually happen?
Level#2: When a man and a woman are both sexually mature, they can reproduce, or have a baby. They do so through sexual intercourse. During intercourse, a man inserts his penis into a woman's vagina and releases sperm. Once released into a female's vagina, sperm cells travel through the cervix and into the uterus. Then, they travel into the fallopian tubes. Fertilization, or the joining of the sperm and egg, usually happens in one of the fallopian tubes. Once the sperm and egg cells have united, a woman becomes pregnant. After fertilization, the egg begins to divide into many cells. This ball-shaped clump of cells travels to the uterus. The cells attach themselves to the wall of the uterus. The cells are now called an embryo.
1. Where does fertilization usually happen and what is the result of it?
2. What happens after fertilization takes place?
3. Where does the "ball-shaped clump of cells" travel to and what does it do?

Once the sperm and egg cells have united, a woman becomes pregnant. After fertilization, the egg begins to divide into many cells. This ball-shaped clump of cells travels to the uterus. The cells attach themselves to the wall of the uterus. The cells are now called an embryo. An organ called the placenta forms in the wall of the uterus. Food, oxygen, and wastes pass between the embryo or fetus and the mother through this organ. However, the blood of the mother and that of the embryo never mix. The capillaries from both mother and embryo lie very close together in the placenta. A rope like structure called the umbilical cord connects the baby to the placenta.
1. Explain what happens after fertilization, where does the egg go, and what does it do.
2. Explain what forms in the wall of the uterus and what its function is
3. Explain what the rope like structure is and what its function is.
