Question
Blood pH varies between 7.35 and 7.45, with targeted value of 7.4. If someone's blood pH begins to decrease, chemoreceptors detect this change and send the information to the brain. The brain analyzes the input and sends out a command to the respiratory muscles, causing breathing rate to increase, which reduces carbon dioxide levels, and thereby increases the pH of her blood.
Name the body part, value(s), or actions in the specific scenario involving pH.
Normal range:________ Set Point:________
Stimulus:_________
Sensor:_________
Integrating Center_________
Effector:_______
Response:___________
Explanation / Answer
Normal range = 7.4.
Set point = Respiratory centre in medulla.
Stimulus =
Sensor= Chemoreceptors.
integrating center = Brain
Effector = Respiratory muscles .
response= Increase in respiratory rate.
