Hypothalamus in brain, thermoreceptors, skin sweat glands, blood vessels, and hormones such as thyroid hormones all coordinate and function together to retain body heat or cause loss of excess body heat.  Thermoregulation in humans  When external temperature rises, sweat glands start producing sweat which on evaporation carries the body heat with it. Blood vessels of skin dilate and release beat to atmosphere. Thyroid hormones decreases production to reduce body metabolic rate. All this is regulated via hypothalamus and receptors. Thirst centre is also activated to cause intake of water to replenish body water loss. Urine output also falls to reduce water loss since excess water is being lost via sweat production and evaporation.  When outside temperature falls, sweat glands decrease sweat production, skin blood vessels dilate and thyroid hormones product...
