Question
Which of the following statements accurately describes homeostasis?
a) The body has the ability to detect change, activate mechanisms that oppose it, and maintain relatively stable internal conditions. b) The loss of homeostatic control can cause illness but cannot cause death. c) Internal conditions are absolutely constant and must not fluctuate within a range. d) The internal state of the body is best described as a static equilibrium, in which there is a certain set point that must be strictly maintained at all times. e) All of these choices are correct.Explanation / Answer
Answer
Homeostasis is the body's ability to detect any change, and activate the mechanism to oppose it and returns the body to its original set point or range. When body senses any changes it activates the mechanism to negate or reverse it. It is the key mechanism for maintenance of health and loss of this homeostatic control can cause illness or death. Moreover the internal conditions are not absolutely constant but fluctuate within a limited range, such as the range of body temperature. This best described as Dynamic equilibrium.
Therefore, the correct answer is option (a).
