Question

select the correct answer.

john is jogging on a winter day. the outdoors temperature is 31 degrees f. yet, his body temperature is 98 degrees f. what term best describes the process causing this difference in temperature?

homeostasis
pathophysiology
fever
hyperthyroidism

Explanation:

Analyze the scenario

The scenario describes John jogging in cold weather (\(31^\circ\text{F}\)) while his body maintains a stable internal temperature of \(98^\circ\text{F}\). This represents the regulation of a stable internal environment despite external changes.

Define the options

• homeostasis: The process by which biological systems maintain stability while adjusting to changing external conditions.
• pathophysiology: The study of disordered physiological processes associated with disease or injury.
• fever: A temporary increase in average body temperature, often due to an illness.
• hyperthyroidism: A condition where the thyroid gland produces too much thyroid hormone.

Select the best term

The process of maintaining a stable body temperature of \(98^\circ\text{F}\) in a cold environment is a classic example of thermoregulation, which is a form of homeostasis.

Answer:

• homeostasis (Correct answer)
• pathophysiology
• fever
• hyperthyroidism
