How does the body produce body heat? - Answers

WebIn Response: It is well established that the primary defect associated with porcine malignant hyperthermia resides within skeletal muscle. It is further established that, during fulminant episodes of malignant hyperthermia, skeletal muscle is the primary source of heat production [1]. Our data and Discussion do not dispute this notion. WebIn humans, heat is primarily generated in the visceral organs - i.e the brain, liver, heart and the skeletal muscles. As mentioned previously, most of the energy produced by the body, though ATP production, is in the form of heat.
