Which of the following is a function of your circadian rhythm?

• A. Your sweat glands secrete sweat and your blood vessels dilate after receptors detect an increase in your core body temperature.
• B. Your body produces more red blood cells at higher elevations.
• C. Injured blood vessels release chemicals to attract platelets to initiate the clotting process. The process is amplified by the secretion of more platelet-attracting chemicals from the existing platelets.
• D. None of the listed responses is correct.
• E. Your body temperature rises and falls every day.

Answer: (E)

Verified step by step guidance

1. Understand the concept of circadian rhythm: Circadian rhythms are natural, internal processes that regulate the sleep-wake cycle and repeat roughly every 24 hours. They are driven by a circadian clock and can influence sleep patterns, feeding behavior, hormone release, and other bodily functions.
2. Identify the function related to circadian rhythm: The key function of circadian rhythms is to regulate daily cycles in physiological processes, such as body temperature, hormone levels, and sleep-wake cycles.
3. Analyze the options provided: Evaluate each option to determine if it describes a function that is regulated by circadian rhythms.
4. Option analysis: The first option describes a thermoregulatory response to temperature changes, not a circadian rhythm function. The second option involves adaptation to altitude, unrelated to circadian rhythms. The third option describes a hemostatic process, also unrelated to circadian rhythms.
5. Identify the correct function: The correct function of circadian rhythm in the context of the options provided is the daily rise and fall of body temperature, which aligns with the natural 24-hour cycle regulated by circadian rhythms.
