Internal Environment And Uniqueness Of The Cell
- 6. Internal Environment Nutrient and waste substances are exchanged between the interstitial fluid and the blood plasma contained in the blood capillaries.
- 9. What is the mechanism which regulates the physical & chemical factors in the internal environment??
- 10. Homeostasis
- 11. Homeostasis Homeostasis is a process that regulates the chemical and physical parameters in the internal environment so that the conditions are always suitable to meet the needs of cells.
- 12. Homeostasis 3 functional components pf homeostatic control system: a receptor- detect a change (stimuli) a control centre- receive message from receptors and process the information an effector- receive message from control centre and carry out the appropriate response.
- 14. The control of body temperature
- 15. Negative feedback mechanism prevent small changes from becoming to large. Homeostasis
- 18. The important of regulating an optimal internal environment Enables the organism to live in wider range of habitats. Metabolic activities and physiological processes can still continue even though the external environment fluctuates substantially. A stable internal environment allows enzymes to function aat an optimal rate.
- 19. The uniqueness of the cell
