When an individual is exposed to extremely low air temperatures the vasculature of the skin will dilate so that blood will flush into skin capillary beds and heat will be dissipated?
This is incorrect. When an individual is exposed to extremely low air temperatures, the blood vessels in the skin will constrict, a process called vasoconstriction. This reduces blood flow to the skin and helps to conserve heat in the body's core.
Why does clotting of blood not take place in uninjured blood vessels?
Blood clotting does occur for blood in uninjured blood vessels due to its insulation from air. Our bodies produce what is called heparin that prevents clotting of blood in vessels. Heparin allows our lungs to transfer oxygen to our blood. When blood is exposed to air it clots so heparin allows the blood to come in direct contact with the air we breath without clotting.

How does the human body close a cut?
our blood has substances called as blood platelets. When blood is exposed to air, the platelets solidify and thus the blood from a cut gets stopped. Having low platelet count in the blood can be fatal even if you have a small wound...
