Across
- 2. This internal mechanism acts as a time conductor toward systemic homeostasis, and is affected by set points.
- 4. This signal takes information from the sensor to the control center, unless the sensor and control center are within the same cell.
- 5. This extrinsic catches decreased blood pressure levels and initiates a simultaneous change through constricting blood vessels and increasing heart rate.
- 9. In a homeostatic control system, this structure helps determine the range in which a body variable should remain in to be considered “normal”, and compares a received value
- 10. This reflex within the aorta walls and carotid sinus are a crucial afferent response to blood pressure levels that have increased above normal.
- 14. This component of the pancreas is an effector in regulating blood glucose levels.
- 17. Before you wake up, your body temperature starts to increase. This is an example of a ____ mechanism.
- 19. What is another name for the control center of a homeostatic system?
- 23. What is the part of extracellular fluid that is integral to exchanging wastes and nutrients?
- 25. An increase in carbon dioxide through exericisng skeletal muscle brings about blood vessel dilation and smooth muscle relaxation, which help bring in more oxygen. This is an example of an ______ control system.
Down
- 1. This extrinsic system catches elevated blood glucose levels and helps to secrete insulin.
- 3. This opposing action seeks to restore a change in a phys
- 6. This detects a change in a stimulus or body variable.
- 7. What is the chemical messenger necessary for the nervous system to organize various organ systems for homeostasis?
- 8. The concept that physiological variables are not fixed, with an example being the regulation of a human’s core body temperature.
- 11. This liquid within blood capillaries aids in maintaining the distribution of body fluids.
- 12. A type of indirect communication that uses chemical messengers between secreting cells.
- 13. This component of the pancreas acts as a sensor for decreased blood glucose levels and releases glucagon.
- 15. The cell or organ that initiates a change to help bring a physiological value back into its normal range.
- 16. This signal takes information in the control center to a designated cell or organ, which is used to execute an action for reestablishing homeostasis.
- 18. Another name for the physiological variable different from its set point.
- 20. Although not contributing to homeostasis, this feedback loop still tends to certain physiological demands by bringing away the variables from the normal range.
- 21. This is the range of a physiological variable deemed normal by the control center.
- 22. A type of direct communication between cells that's comprised of ions and molecules.
- 24. Located externally to a system or an organ, this control system helps maintain coordination of several organs for homeostatic purposes.
