Unit 4 -- Homeostasis
Across
- 4. an individual living thing
- 6. system responsible for protection against disease; stores and generates white blood cells
- 8. the basic unit of structure and function of a living organism
- 10. the process by which different types of cells develop
- 13. an environmental condition that is sensed by a living organism
- 14. system of bones responsible for structure, movement, organ protection, and production of red blood cells.
- 16. a group of tissues that together perform a function
- 21. widening of blood vessels to increase bloodflow
- 22. system that includes the brain, spinal cord, and nerves; responsible for sensing stimuli, making decisions, and initiating responses
- 23. a response to a stimulus
- 24. narrowing of blood vessels to decrease bloodflow
- 25. the maintenance of internal systems
- 26. systems that filter and rid the body of wastes
Down
- 1. mechanism that increases the likelihood of an event to continue
- 2. system responsible for movement of the body, and the movement of fluids and digestive products within the body
- 3. system responsible for the intake and breakdown of food, the absorption of nutrients, and the elimination of some wastes.
- 5. system responsible for the development of offspring; the only system not required for homeostasis
- 7. control of body temperature
- 8. system responsible for delivering nutrients, hormones, and oxygen to cells and wastes away from cells.
- 9. the result of the decision made at the sensing of a stimulus
- 11. skin and hair that acts as a barrier to prevent water loss, prevent UV radiation damage, and provides thermoregulation
- 12. the point at which stem cells are committed to becoming only one type of cell
- 15. mechanism that decreases the likelihood of an event to continue
- 17. system responsible for the exchange of oxygen and carbon dioxide with the environment
- 18. a group of organs that together perform a function
- 19. a group of like cells that perform a function
- 20. system that includes glands that release hormones into the bloodstream; responsible for growth, development, and metabolism
