After you exercise for a while, you may notice that your skin turns red. (A) How is the blood flow in your limb changes as a response to the exercise? When your skin turns red, how has the temperature changed at the skin surface (Tskin)? (B) During exercise, does the total heat generation rate inside your body increase or decrease from that in normal conditions? (C) What is the relationship between the total heat generation rate and the total heat loss from the skin surface to the environment by convection? Neglect sweating and radiation. (D) The total heat loss from the skin surface to the environment is hA(Tskine-Tair). Based on this convection equation and results in (C), how has the skin temperature changed during exercise? Does Iskin increase or decrease from that in normal conditions? Is this consistent with that in (A)?

Question
Transcribed Image Text:**Understanding Skin Redness During Exercise**
After you exercise for a while, you may notice that your skin turns red. Let's explore why this happens:
---
**(A)** How does blood flow in your limbs change in response to exercise? When your skin turns red, how has the temperature changed at the skin surface (\(T_{\text{skin}}\))?
**(B)** During exercise, does the total heat generation rate inside your body increase or decrease compared to normal conditions?
**(C)** What is the relationship between the total heat generation rate and the total heat loss from the skin surface to the environment by convection? Neglect the effects of sweating and radiation.
**(D)** The total heat loss from the skin surface to the environment is given by \( hA(T_{\text{skin}} - T_{\text{air}}) \). Based on this convection equation and the results in (C), how has the skin temperature changed during exercise? Does \(T_{\text{skin}}\) increase or decrease from that in normal conditions? Is this consistent with your observations in (A)?

Feel free to explore these questions to better understand the physiological changes occurring during exercise.
Expert Solution
Step 1: Determine how he blood flow in limb and total heat generation in body while exercise.
To Find:
How does the blood flow in your limb change in response to the exercise? When your skin turns red, how has the temperature changed on the skin surface.
The total heat generation rate inside your body increases or decreases from that under normal conditions.
The relationship between the total heat generation rate and the total heat loss from the skin surface to the environment by convection
