Question

The term dynamic homeostasis refers to the fact that

• A. Homeostatic mechanisms keep physiological responses from fluctuating.
• B. Homeostatic mechanisms allow for physiological responses to slightly fluctuate within a normal range.
• C. Homeostatic mechanisms keep fluctuations in physiological responses right at set point.
• D. Homeostatic mechanisms allow for large fluctuations that will reset the set point.

Answer 1

Answer: (A)

Homeostatic mechanisms keep physiological responses from fluctuating.

The ability of the body to regulate its internal physiological processes in order to maintain the equilibrium is called the dynamic equilibrium. It is performed to keep the physiological responses from fluctuating with the external conditions of the environment. Different organ system work under the regulation of hypothalamus and medulla maintain the dynamic homeostasis.

Hence, the correct answer is 'Homeostasis mechanisms keep physiological responses from fluctuating'
