Question

page(s) 495-498 25.1. explain how cells communicate with each other via the endocrine system. wim hof, also known as the \iceman,\ used breathing and meditation techniques to train himself to withstand freezing temperatures. he also claimed to be able to consciously modulate his autonomic nervous system and immune system. if hof’s claims were true and you examined him as he performed these techniques, what would you find in hof compared to others who had not trained themselves? correct answer(s) lower adrenaline levels more active adrenal glands fewer cytokine receptors activated higher blood glucose greater innate immune response

Explanation:

Wim Hof's claimed conscious modulation of the autonomic nervous system (ANS) and immune system via breathing/meditation implies reduced stress responses (lower adrenaline, a stress hormone from the ANS) and potential enhanced immune regulation (fewer activated cytokine receptors, as excessive cytokine activation is linked to inflammation; his techniques may dampen this). Higher blood glucose, more active adrenal glands, and greater innate immune response are inconsistent with controlled ANS/immune modulation.

Answer:

lower adrenaline levels, fewer cytokine receptors activated
