Human Reproductive System
Sperm duct
I. Human Reproductive System
Open Sciencesaurus to 099-102.
1. Define specialized cells.A specialized cell is a cell that takes on a special job.
2. What is the name of the specialized cell in females?egg cells
Human Reproductive System
3. What is the name of the specialized cell in males?
sperm cells4. Why is genetic material
important?Because genetic material
contains the information that an organism needs to form, develop, and grow.
Human Reproductive System
5. What do the specialized cells do?They provide genetic material.
6. What is the role of hormones in sexual development?Hormones produced in the endocrine system signal the start of sexual development.
Human Reproductive System
7. What human body system makes hormones?Endocrine system
Female Reproductive System
8. Copy and label the diagram in section 100.
9. What are the 2 functions of the female reproductive system?A. To produce egg cells.B. To protect and nourish the
offspring until birth.
Female Reproductive System
10. Where are the egg cells stored?
The egg cells are stored in the ovaries.
11. How do the ovaries know to release an egg cell?
The ovaries release an egg cell when pituitary gland releases hormone.
Female Reproductive System
12. Define menstruation.Flow of blood and tissue from body through vagina
13. How long does menstruation last?For about 5 days
14. How often does menstruation occur?Occurs every 28 days
Female Reproductive System
15. Describe the process of menstruation (the path the egg cell takes beginning with the ovary) if fertilization does NOT take place.
During menstruation, egg cell travels from ovary, through fallopian tube, through uterus, through vagina.
Male Reproductive System
16. Copy and label the diagram in section 101.
17. Where are sperm produced? produced in testes
Male Reproductive System
18. What are the 2 things the hormone produced in the testes do?
A. Controls development of sperm.B. Causes development of facial hair and deep voice.
Male Reproductive System
19. When do males begin producing sperm?Sometime during adolescence
Male Reproductive System
20. What is the name of the fluid sperm travel in? semen
21. How many sperm cells are in 1 drop of semen?several million
Reproductive System22. List and explain the 3 parts of
reproduction.A. Fertilization – When 1 sperm cell
joins the egg cell.B. Pregnancy – 9 months for
fertilized egg cell (embryo) to develop fully (fetus).
C. Birth – fully developed fetus ready to be born.
Reproductive System23. Define fertilization.
When 1 sperm cell joins the egg cell. Occurs in fallopian tubes.
Reproductive System24. During fertilization, list the
path the sperm takes, beginning with the testes.From the testes, through the penis, through the vagina and uterus, and into a fallopian tube.
Reproductive System25. Where does fertilization take
place?In a fallopian tube.
Reproductive System26. After fertilization, list the path
the fertilized egg takes.Fertilization takes place in fallopian tube, cell division begins and then fertilized egg moves to the uterus where it attaches to the lining.
27. Define embryo.Name of fertilized egg after cell division occurs.
Reproductive System28. How long does pregnancy
last?9 months
29. Why is the placenta important?Oxygen and nutrients from the mother’s body move through placenta and umbilical cord to the growing embryo.
Reproductive System30. List and define the 3 steps of
birth (labor and delivery).A. Labor – muscle contractions in
uterus every 10 to 30 minutes.B. Delivery – fetus pushed out of
uterus, through vagina, and out of body.
C. Birth of placenta – after offspring born, placenta separates from uterus and leaves mother’s body.
