Wade and his wife desperately need some exercise these days to work off all those extra pounds they added during the COVID-19 pandemic.  So, they decide to go for a brisk walk in their neighborhood, which is nestled in the hills just west of Atascadero.  As they begin their walk, their blood pressure is too low to support their elevated level of activity, especially as they start to follow their street as it climbs a steep, nearby hill.   In the space provided below, describe the steps of the negative feedback loop that Wade’s body will use to solve this problem and return him to homeostasis.  Make sure you focus on how the majority of his arterioles must change to solve this problem. You may list the generic steps and give a brief description, like this: 1) Stimulus – type your description 2) Sensor – type your description etc., etc., until you arrive at the desired Response Make sure to list all the generic steps of a feedback loop for this class AND describe the specific physiological details for each of those steps EXACTLY as if you were drawing a feedback loop diagram.  Provide as much physiological detail as possible at each step (e.g., effector cells, receptor types, signal molecules, the step-by-step “action” that fixes the problem, etc.).
