A decrease in pH and increase in carbon dioxide

Question 31

You also have receptors where?

Answer 31

In muscles and joints

Question 32

When are the receptors in your muscles and joints stimulated?
What will these receptors stimulate?

Answer 32

When you exercise; the respiratory center

Question 33

Why is it important to breathe quicker when you exercise?

Answer 33

So you can take in more oxygen and blow out all the acid that has built up

Answer 35

Receptors that are protective in the lungs and help blow off the irritant

Question 36

What do irritant receptors do to the respiratory center when stimulated?

Answer 36

They suppress the respiratory center to slow down respiration
