Read the following scenario and determine the parts of the homeostasis feedback loop.
When a human increases physical activity, the amount of fuel burned in its cells also increases, which in turn increases the concentration of dissolved CO2 in the blood. The CO2 reacts with water in the blood to make a weak acid, which lowers the pH of the blood. Sensory cells in the aortic arch register this drop in pH and send sensory information to the medulla oblongata of the brain. The medulla oblongata sends signals to the diaphragm to increase respiration. This will clear the CO2 from the bloodstream.
A. Name the stimulus in this scenario.
B. Explain what a receptor is in the homeostasis feedback loop and name the receptor in this scenario.
C. Explain what an integrating center is in the homeostasis feedback loop and name integrating center in this scenario.
D. Explain what an effector is in the homeostasis feedback loop and name the effector in this scenario.
