The heat flow is best described as an exchange of heat between the system and the surroundings.

Explanation:

Heat is a form of energy which is transferred spontaneously from a hotter body to a cool body as a result of temperature differences between the substances. In the problem, it can be said that heat moves from the surroundings which may be a fractured knee of the athlete to the ice packs.
