You perform an experiment in which you measure skin temperature in two different body areas, cool the skin of those body areas with ice, and measure the time it takes for each skin area to recover to its baseline temperature before cooling. Areas of skin which are well-supplied with blood vessels would be expected to recover baseline skin temperature at _____________ as compared to areas with fewer blood vessels. Group of answer choices none of the above a slower rate a faster rate the same rate
Added by Shannon A.
Step 1
When skin is cooled, the temperature drops. Recovery to baseline temperature depends largely on blood flow because blood carries heat from the body's core to the skin. Show more…

DATA ANALYSIS 1. Is the baseline temperature recovered within the 2 minutes during which data is collected? Estimate how long it would take for full recovery to be achieved for each of the two runs. Relate this to everyday experiences where you have been exposed to cold. 2. Which area of skin tested (upper arm or face) had the most rapid recovery of temperature after cooling? Explain this result. 3. Alcohol causes dilatation of arterioles and a sensation of warmth. Would you recommend that someone who is stranded in the snow drink alcohol to keep warm? Why or why not? 4. A condition called hyperthermia (heat prostration) can result when the body's homeostatic mechanisms are no longer adequate to counter the effect of high external temperatures. On the basis of what you know about vasoconstriction and vasodilation as methods of temperature regulation in the body, describe the skin color of someone who is in the first stages of hyperthermia. EXTENSION 1. Perform the procedure on different areas of the body (i.e., over large muscles, such as the thigh and calf muscles; or over areas with little subcutaneous fat, such as the palm, kneecap, and shin). Compare your results with the result obtained in the original experiment. 2. Perform the procedure placing a blanket over the area on which the sensor is attached. Does this alter the recovery time? Data Run | Baseline Temp. (°C) | Slope / rate (°C/s) | Baseline Temp w Ice (°C) | Slope / rate w Ice (°C/s) Upper Arm | 30.1 | — | 27.1 | 0.104 Cheek | 33.1 | — | 28.5 | 0.0345
