Summary Introduction
Introduction: The hypothalamus is a small region in the brain located near the pituitary gland. When outside temperature declines, thermoreceptors in their skin send action potential to the hypothalamus; the brain region is responsible for thermoregulation. A signal from the hypothalamus causes vessels that deliver blood to the skin to contract, so less

- 1. The hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? a. A decrease in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. b. An increase in blood glucose concentration stimulates insulin secretion, which in turn into lowers blood glucose concentration. c. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. d. An increase in blood glucose stimulates insulin secretion, which in turn further increases blood glucose concentration.arrow_forward1. Which structure produces secretions that regulate E and H? a.
