Praxis 5511 Practice Test Practice Question
When a person is exposed to warm conditions, the circulation of blood to capillaries near the surface of the skin increases. Which of the following occurs as a result of the change in blood circulation?
Correct Answer: A
Rationale: Increased blood circulation to capillaries near the skin's surface enhances heat transfer from the body to the surroundings through radiation and convection, facilitating cooling.
Option B is incorrect because heat absorption does not reduce sunburn; rather, it can increase skin temperature and damage.
Option C is misleading, as gas exchange primarily occurs in the lungs, not through the skin.
Option D is not accurate; while humidity can affect the skin, increased blood flow does not lead to water absorption from the air into the body.
