The Congress and President of the United States delegate specific authority to government agencies to regulate the complex facets of the modern American federal state. Also, most of the 50 U.S. states have created similar government agencies.The term government agency or administrative agency usually applies to one of the independent agencies of the United States government, which exercise some degree of independence from the President's control.lso, most of the 50 U.S. states have created similar government agencies.

The skin is the largest organ in the human body. Its main job is to maintain the body's temperature, which means that sweat is created to cool the body, and goosebumps or raised hair occur to trap heat in the body. Along with sweat glands, the skin contains oil glands.
For your question, in cold conditions, the small blood capillaries on the surface of your skin constrict to prevent blood flow to them. Since blood carries body heat, it prevents heat loss through convection, conduction and radiation from the skin surface. Remember that the skin is the biggest organ in our body and hence has the largest surface area, heat can be lost/kept effectively. The reverse happens for warm conditions. The blood vessels dilate and allow blood flow to skin surface and heat is lost through convection, conduction and radiation. A little bit of physics involved: Heat energy travels from an region/object of higher temperature (skin) to a region of lower temperature (surrounding environment).
