Question

Inside human body ,which of the following is responsible for heat transfer,

• A. conduction
• B. forced convection
• C. free convection
• D. none of the above

Answer 1

The correct option is B forced convection

Forced convection requires external force or energy to transfer heat from a body.

Heart is the best example of forced convection in human body. Heart acts as a double pump. First pump carries oxygen-poor blood to your lungs, where it unloads $C{O}^2$ and picks oxygen. It then delivered oxygen-rich blood back to heart. The second pump delivers oxygen-rich blood to every part of the body.
