  1. The Human Body (HB Chapter 1) Test Review

  2. Directs the cell’s activities and holds information that controls a cell’s function. nucleus

  3. Made of clear, jellylike substance that contains many cell structures. cytoplasm

  4. Three things that work together to make your body move. • muscles • bones • nerves

  5. Three stages of digestion of food. • breakdown • absorption • elimination of wastes

  6. System that breaks down food so the body can use it. • digestive system

  7. System that transports oxygen. • circulatory system

  9. Covers the surface of your body, inside and out. epithelial tissue

  10. Carries electrical messages back and forth between the brain and other parts of the body. nervous tissue

  13. Perform more complex jobs than tissues. • organs

  14. To bend a joint, one muscle does this while another muscle returns to its original length. • contracts

  15. Basic unit of structure and function in a living thing. cell

  17. Provides support for your body and connects all its parts (ex. fat). connective tissue

  18. Forms the outside border of a cell. cell membrane

  19. Body tissue that contracts, or shortens, making body parts move. muscle tissue

  20. Inner framework that includes all the bones in your body. skeleton

  21. Attached to the bones of your skeleton and provide the force that moves your bones. skeletal muscles

  22. Place in the body where two bones come together. joint

  23. Substance that you get from food and that your body needs to carry out processes, such as contracting muscles. nutrient

  24. Process where nutrients move from the digestive system into the bloodstream. absorption

  25. Organs that release chemical signals directly into the bloodstream. glands

  26. A signal in the environment that makes you react. stimulus

  27. What your body does in reaction to a stimulus. response

  28. Chemical signals released by the endocrine system and affect growth and development. hormones

  29. The condition in which an organism’s internal environment is kept stable in spite of changes in the outside environment. homeostasis

  30. Disrupts homeostasis. • long-term stress

  31. The reaction of your body to possible threatening, challenging, or uncomfortable events. stress
