Using the following 2 examples of negative feedback, identify each component of the control loop and list them in the tables provided. 1. Example 1: A mountain climber has traveled to Tibet to prepare for climbing Mt. Everest. Part of the preparation involves acclimating to the higher altitude and lower oxygen concentration in the air. The lower oxygen concentration in the air results in a lower blood oxygen level that is detected by chemoreceptors in their kidneys. The kidneys respond by producing a hormone called erythropoietin (EPO). EPO travels in the blood and causes red bone marrow to increase the production of red blood cells. The increased number of red blood cells allows for blood oxygen levels to return to homeostasis. Example 2: A person stands up quickly after laying on the couch for several hours. When they stand up, they feel dizzy due to a sudden drop in blood pressure to their brain. The drop in blood pressure is detected by baroreceptors located in large arteries. The baroreceptors send a signal to the brainstem. The brainstem then communicates to the heart causing an increase in heart rate. The increased heart rate acts to increase blood pressure back to homeostasis.
