Cells and Body Systems

1. allows movement
2. waste removal
4. growth of tumours, which take up space in the lungs, making breathing difficult
8. hair like extensions that protrude from the surface of some unicellular organisms and some cells in multicellular organisms
9. coordinates and controls all organs and organ systems; detects, processes, and responds to stimuli
11. substance created by the body to carry out chemical digestion
12. transport system reaching every cell of the body; delivers nutrients absorbed by the digestive system and oxygen absorbed by the respiratory system in every cell
13. large muscle below the lungs that helps move air in and out of the lungs; part that changes the size of a camera's aperture; it varies the amount of light that reaches the film
14. all the life processes that take place in the cell; includes energy-using and energy-creating substances
15. protects body's internal environment from the external environment "skin"
17. breaks down the food you eat into parts small enough to be absorbed and transported throughout the body
18. covers the surface of the body and internal organs and lines the inside of some organs
21. supports and connects different parts of the body
22. the basic unit of life
23. contents of the cell the cell membrane excluding the nucleus; contains nutrients the cell needs to survive

1. made of more than one cell
2. removes chemical and gaseous wastes from the body; involves organs from other bodily systems
3. thin structure that encloses all the contents of plant and animal cells
5. organelles that convert sunlight into food
6. outer covering of a cell that provides strength and support
7. technique for separating solutions that involves boiling and condensation
10. physical breakdown of food into small particles
16. moves bones; moves organs that contain muscle tissue
19. organelles that convert energy the cell receives into a form it can use
20. tissue of the brain, spinal chord, and nerves.
