Sample item

Which response is most important for heat loss during exercise in a warm environment?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Sweating with evaporative cooling

Evaporation of sweat removes heat from the skin, becoming the dominant heat-loss mechanism when ambient temperature approaches body temperature.

Option by option

  • A. Sweating with evaporative cooling (correct)

    Correct: sweat evaporation transfers heat away from the body.

  • B. Shivering thermogenesis

    Shivering generates heat during cold exposure.

  • C. Increased thyroid hormone secretion immediately

    Thyroid hormone does not provide immediate cooling during exercise.

  • D. Cutaneous vasoconstriction

    Vasoconstriction conserves rather than dissipates heat.

What is the answer to this Physiology question?

The best answer is A, Sweating with evaporative cooling. Evaporation of sweat removes heat from the skin, becoming the dominant heat-loss mechanism when ambient temperature approaches body temperature.

Why is "Shivering thermogenesis" not the answer?

Shivering generates heat during cold exposure.

Why is "Increased thyroid hormone secretion immediately" not the answer?

Thyroid hormone does not provide immediate cooling during exercise.

Why is "Cutaneous vasoconstriction" not the answer?

Vasoconstriction conserves rather than dissipates heat.

What concept does this question test?

It tests Temperature regulation in Physiology. The correct option holds because: Correct: sweat evaporation transfers heat away from the body.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study Temperature regulation?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
