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.
Short answer:
Valve which permits blood to flow from the right atrium to the right ventricle is tricuspid valve
Long answer:
The right side of the heart has lower pressure compare to the left side. There is a valve that support the lower pressure so the blood can move easily from the right atrium to the left ventricle. The valve is called tricuspid valve. It's called "Tri" because there are 3 flaps/leaflets on the valve.
For your information, the left side of the heart only has 2-leaflet valve, which make smaller circular opening compare to the 3-leaflet valve on the right side. That's because the left side has higher pressure than the right side.
