Answer:
The type of heat exchange that is occurring are as follows: convective, radioactive, evaporative, and conductive.
Explanation:
In convective heat exchange it is due to the fact that the day is windy. This type of exchange is classified as heat loss through the movement of air molecules in contact with the skin. In the radioactive heat exchange it is by UV waves that come from the sun, which transfer heat to the person. The heat exchange by evaporation occurs through the sweating process, thanks to the wind that would be cooling the person. And finally, in conductive heat exchange it refers to the fact that the person is losing heat through physical contact with the park bench.
Answer:
An increase in capillaries helps to increase healing by improving blood flow to the site of injury. Improving blood flow provides muscles with an increase in oxygen that gives muscle energy and so reduces muscle fatigue and weakness. An improvement in blood flow also supplies muscles with an increase in nutrients.
Diffusion, the most widely-used mechanism, allows the flow of small molecules across capillaries such as glucose and oxygen from the blood into the tissues and carbon dioxide from the tissue into the blood.
