AAbout 37 degrees Celsius
BAbout 39 degrees Celsius
CAbout 38 degrees Celsius
DAbout 40 degrees Celsius
Answer & Solution
Correct answer: C. About 38 degrees Celsius
1. Blood flowing along vessel walls meets friction and resistance, and friction produces heat.
2. Blood therefore runs slightly warmer than the internal body temperature reading.
3. Blood sits at about 38 degrees Celsius, against about 37 degrees Celsius for the internal reading.
4. The figure of 37 degrees Celsius is the internal body reading itself, which is the obvious trap here.
