receptors in the skin are involved in human thermoregulation?, Temperature receptors., What happens to the rate of sweating when body temperature falls below the normal set point?, The rate of sweating decreases., How does the hypothalamus respond to signals from temperature receptors in the skin?, It coordinates the appropriate corrective mechanisms to maintain temperature., Hormones are _____ substances that alter the activity of specific organs., Chemical, Where are the hormones insulin and glucagon produced?, The islets of Langerhans in the pancreas., What is the effect of insulin on the activity of its target organs regarding glucose?, It promotes the removal of glucose from the blood., What is the effect of glucagon on the activity of its target organs regarding glucose?, It promotes the release of glucose into the blood., Under what condition is glucagon typically released into the blood?, When blood glucose concentration is lower than normal., Under what condition is
