Homeostasis
Across
- 1. Used to send information from the control center to the effectors
- 3. processes rely on ______ loops that monitor the changes in the internal atmosphere and react to them.
- 5. is the ability of an organism to sustain a stable internal environment when external conditions change
- 6. Cells exchange materials from the intracellular fluid, with the ______ fluid (extracellular space) and blood (specifically plasma)
- 8. Sends the information from the sensor to the control center/integrator
- 10. Homeostasis is necessary for the support and life of _____ organisms
- 11. (cells/organs) that need to perform an action to help restore homeostasis
- 12. Where all hormone-secreting glands)

- 16. example of negative feedback is regulating ______ concentration
- 18. control systems are “built-in” to an organ or tissue.
- 21. cells in the pancreas that release insulin.
- 22. ______integratestergates information with other information
- 23. feedback that does NOT contribute to Homeostasis, but to specific physiological needs
Down
- 2. In order to maintain homeostasis, the cells of the body need to “_______ to” one another
- 4. high blood glucose is detected by the ______ system
- 7. A change in a controlled variable ________ a response that drives the variable in the opposite direction of the initial change, thus opposing the change
- 9. A change in a controlled variable triggers a response that drives the variable in the opposite
- 12. control systems are contained outside of an organ or system, permitting coordinated regulation of several organs
- 13. the β-cells are monitoring the levels of glucose in ______.
- 14. A _______ control system is an interconnected network of body components that work together to maintain a given factor relatively constant
- 16. The cells communicate through these junctions
- 17. If glucose levels are too high, they release ______ that goes and acts on muscles, fat cells, and other cells.
