After spending several days at a high altitude,where oxygen pressure is low,a person will begin to produce more red blood cells,which enhances the ability of his/her blood to carry oxygen to the tissues.Which of the following control mechanisms best describes this response?
A)Developmental acclimatization
B)Positive feedback
C)Physiological acclimatization
D)Feedforward regulation
E)None of the choices are correct

Question

Quizplus · Accepted Answer

Physiological acclimatization refers to changes in the body's physiological mechanisms in response to environmental factors. In this case, the low oxygen pressure at high altitudes triggers the body to produce more red blood cells, which is a physiological response that enhances the oxygen-carrying capacity of the blood. Developmental acclimatization refers to long-term changes in the physiological mechanisms that occur during development or over multiple generations, while positive feedback and feedforward regulation are control mechanisms that maintain homeostasis in the body, but do not describe this specific response to high altitude.
