The human body's arterial blood pH is tightly maintained around 7.4 by buffering agents that bind hydrogen ions to stop any change in pH.If an acid-base imbalance overcomes the buffer system,the body changes the ventilation rate,or the rate at which gas enters or leaves the lungs.Changing the ventilation rate changes the concentration of CO₂ in the blood,which alters the pH of the blood.In this case,the muscles that control the ventilation rate are acting as the: A)homeostatic challenge. B)sensor. C)effector. D)integrator. E)set point.

Question

Quizplus · Accepted Answer

The muscles that control ventilation rate act as the effector in the body's response to an acid-base imbalance. The effector is responsible for carrying out the response to a stimulus, in this case, changing the ventilation rate to alter the concentration of CO2 in the blood to maintain a steady pH.
