What role does brown adipose tissue (BAT) play in human thermogenesis during cold exposure? How do these cells help to regulate body temperature?

Brown adipose tissue is a type of specialized tissue, and its main function is to maintain human body temperature by produce heat (Cypess and Kahn 2013). It does this through non-shivering thermogenesis. ‘Its thermal capacity allows humans to live in cold conditions without needing to depend on shivering muscles (Cypess and Kahn 2013). Shivering muscles uses more energy per unit of heat when compared to the non-shivering thermogenesis carried out by brown adipose tissue. Brown adipose tissue is able to do this since it has an abundance of mitochondria which, allows it to produce a significant amount of thermal energy to maintain body temperature in cold climates (Townsend and Tseng 2014). …show more content…
all 2012). It has shown that cold exposure the activity of Increases Brown adipose tissue, which produces heat (Cypress et. all 2012). Brown adipose tissue is entirely responsible for non-shivering thermogenesis during cold acclimation and is activated when humans are in the cold.
Brown adipose tissue has an abundance of mitochondria which allows it to produce a significant amount of energy, which is turned into thermal energy to maintain body temperature in cold climates. Brown adipose tissue is able to use fatty acids and glucose as fuel, the tissue can also switch fuel sources without increasing overall energy expenditure (Townsend and Tseng 2014). Therefore, Brown adipose tissue is extremely important in human thermogenesis during cold exposure. This is because brown adipose tissue causes non-shivering thermogenesis, which
