Respiratory Compensatory Mechanisms

Question 1

what do chemoreceptors monitor?

Answer 1

02, c02, and H+ blood conc ie pH

Question 2

Where are chemoreceptors found?

Answer 2

1. similar places to baroreceptors ie respiratory centre in base of brain (central chemorec)
2. peripherally: carotid and aortic bodies

Question 3

what do central chemoreceptors respond to?

Answer 3

changes in C02 levels and in pH

Question 4

what do peripheral chemoreceptors respond to?

Answer 4

changes in 02, along with c02 and pH to a lesser degree

Question 5

both types of chemoreceptors stimulate what receptors?

Answer 5

stretch and irritant receptors in lungs; also higher and emotional centre of brain have role in controlling breathing
