B5 Homeostasis and Response Part 1.
4.5.1 Homeostasis
Regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes.
Human
Blood Glucose concentration ( 90 mg/100cm3 blood)
Body temp (37*C)
Water levels (pH = 7.2)
Essential for bodies internal conditions to remain within these limits so proteins and enzymes can function correctly.
Automatic control systems:
Nervous or Chemical responses
Systems include...
Receptors: cells that detect changes in the environment (stimuli)
Coordination centers: receive and process information from the receptors (e.g. brain, spinal cord and pancreas.
Effectors: bring about responses that restore optimum levels (Muscles or glands)
Questions
Homeostasis is the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes.
Nose and Tongue detect Chemicals
Ears detect body position.
The advantages of having pain receptors in the skin are detecting extremes in temperature and pressure and injury-related chemicals.
The response in a fire alarm sequence is the ears hearing the alarm and
then you move out of the building.
Receptors in your ear detect the noise of the notification, which is the stimulus. These receptors transfer the information to the brain which coordinates the information and then decides. The brain then sends the information and then you either pick the phone up or you leave it.
