Name: ____________________________ Science 7 - ____ Johnston Date: _________________________ Ch. 16 Test Review – Part 1 Section 1: The Endocrine System 1. The _________________________ system produces chemicals that control both daily activities and long-term changes through hormones. 2. The endocrine system controls the amount of a particular _______________________ in the blood by stopping its release when it reaches a certain level. 3. The way the endocrine system maintains ______________________ is often compared to a heating system that turns a furnace on and off to control a room’s temperature. 4. The way that the endocrine system stops the release of a hormone when it reaches a certain level is an example of _________________________ ___________________________. 5. The _____________________________ is the endocrine gland that links the endocrine system and the nervous system. 6. Hormones cause changes only in specific body organs because a hormone interacts only with _____________________ cells, which fit together with that hormone. 7. The endocrine gland called the ________________________ gland communicates with the hypothalamus to control many body activities. 8. The thyroid and pituitary are part of the ___________________________ system. **Understand how negative feedback controls hormone levels in the blood. Section 2: The Male and Female Reproductive Systems 9. The joining of a sperm and an egg is called _______________________________. 10. The ________________________ is the structure formed when fertilization occurs. 11. After it leaves the fallopian tube, a fertilized egg develops in the ________________________. 12. A mature egg is released from the ovary during a process called _______________________. 13. In a female’s body, an egg develops in an ovary, and the uterus prepares for the arrival of a fertilized egg during the ________________________________ cycle. 14. During the menstrual cycle, the lining of the _____________________ builds up with extra blood and tissue to prepare for a fertilized egg. 15. Sperm are produced in the ___________________________. 16. Eggs are produced in the _______________________________. 17. Human eggs are usually fertilized in the ________________________ _______________. 18. When a human egg is not fertilized, extra blood and tissue from the uterus are released through the vagina in a process called ___________________________________. 19. The hormone ____________________________ controls the development of male characteristics. Section 3: The Human Life Cycle 20. The first 9 months of human development in the correct order is ____________________, _________________________, and _____________________________. 21. Nutrients from the mother pass to the developing embryo through a membrane called the _____________________________. 22. During the stage of childbirth called _________________________, strong muscle contractions of the uterus cause the cervix to enlarge. 23. The stage of development called _________________________ lasts from ages 2 to about 12. 24. The main event that happens during _______________________ is that an individual’s body becomes able to reproduce. 25. During the stage of childbirth called afterbirth, the ___________________________ leaves the mother’s body. 26. The placenta __________________ (can/cannot) protect an embryo from alcohol and other harmful substances that might be present in the mother’s blood. 27. The baby is pushed out of the uterus during ________________________, or the second stage of birth. 28. Children become adults physically and mentally during the stage of development called _________________________________. 29. The ________________________ is the structure formed during pregnancy through which the fetus receives oxygen and food from the mother and through which wastes pass from the fetus to the mother. 30. During delivery, the _______________________ undergoes strong muscular contractions that push the baby out of the uterus, through the vagina, and out of the mother’s baby. **Be familiar with the parts of the developing fetus and the structures of the female reproductive system.
