Thyroxine is a hormone that is secreted by the thyroid gland to the blood stream. BMR is the basal metabolic rate that is affected by the levels of thyroxine hormone in the system. Hypophysectomy is the removal of the pituitary gland from an organism, in this case the rats. BMR rate of the rat seemed to increase with the injection of thyroxine however the BMR was still lower than the BMR of a normal rat with the thyroid gland and the dose was too low.
