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. What can happen when a man and a woman are both sexually mature?





2. How do a man and a woman reproduce together?





3. What happens during intercourse that can produce a baby?





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. What can a sexually mature male and female do and how do they do it?





2. What happens during sexual intercourse between a man and a woman?





3. Where does sperm travel to once it is released during intercourse?








Level#3: 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. 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 and how a sexually mature woman and man reproduce.







2. Explain where sperm travels to so that it can fertilize a woman's egg.







3. Explain what fertilization is and where it takes place.
