Regulation of blood sugar ; when blood sugar is below normal/90 mg/100 cm3 glucagon ; triggers the conversion of glycogen to glucose in the liver; the glucose is released into the blood stream. When blood sugar is in excess above normal/10 mg/100cm, insulin; causes the liver to convert glucose excess to glycogen ; which is stored. Production of heat energy ; by increasing the rate of metabolic activities; Excretion of bile pigments ; produced due to breakdown of worn out red blood cells; Deamination/removal of amino group of excess amino acids to form urea; and detoxication/poisonous/toxic substances;
Sweat glands excrete urea; excess water; and salts; hence maintaining salt & water balance in the blood. Evaporation of sweat; cools the body due to loss of latent heat of vaporization; when the body temperature rises ; blood vessels in the skin vasolidate; allowing more blood to flow near the skin surface; thus heat is lost to the environment by radiation/convection. The erctor pili mucle relaxes hair flattens ; in a hot environment reducing insulation; hence heat is lost from the body by radiation/convection; to the environment.
