7. Dehydration is a condition in which the quantity of water leaving the body is greater than the quantity entering the body. The diagram below outlines the stimulus-response model when a person suffers dehydration.

For the following physiological events, identify the following components of homeostatic control Variable Stimulus Receptor Input Control center Output Effector Response Thyrotropin-releasing hormone (TRH) is a hormone regularly released by the hypothalamus. Once released, it then stimulates the anterior pituitary gland causing it to release thyroid stimulating hormone (TSH). TSH then stimulates the thyroid gland to release the hormones T3 and T4. T3 and T4 have two main effects. First, they increase overall metabolism. Secondly, T3 and T4 can bind to these receptors on the hypothalamus and anterior pituitary, inhibiting the production of TRH and TSH respectively.
