heat loss, physical causes

heat loss, physical causes,

n.pl the physical factors that influence heat loss: radiation, convection, and conduction; evaporation from the lungs, skin, and mucous membranes; the raising of inspired air to body temperatures; and the production of urine and feces.

heat production, metabolic causes,

n.pl the chemical factors of the body that cause heat production: specific dynamic action of food, especially protein, that results in a rise of metabolism; a high environmental temperature that, by raising temperatures of the tissues, increases the velocity of reactions and thus increases heat production; and stimulation of the adrenal cortex and thyroid glands by the hormones of the pituitary glands.
