Question
what is the answer?

Transcribed Image Text:**In conditions of hyperthermia:**
**Group of answer choices:**
1. Blood vessels near the skin will constrict
2. Shivering will occur
3. Sweating will occur
4. Heart rate will decrease
**Explanation:**
In hyperthermia, the body's temperature regulation mechanisms are activated to dissipate excess heat. Here are the correct responses to the above choices:
- Option 3, "Sweating will occur," is a typical physiological response to cool down the body during hyperthermia.
- Option 1, "Blood vessels near the skin will constrict," is incorrect because vasodilation (widening of blood vessels) usually occurs to release heat.
- Option 2, "Shivering will occur," is a mechanism associated with generating heat, not cooling.
- Option 4, "Heart rate will decrease," is incorrect as the heart rate typically increases to facilitate heat dissipation.
