Question 1

Location of chemoreceptors

Answer 1

Carotid and aortic bodies

Question 2

Location of the carotid body receptor

Answer 2

Found at the point where the common carotid arteries divide

Question 3

Location of aortic bodies

Answer 3

Small clusters of chemosensitive cells that lie adjacent to the aortic arch near the heart

Question 4

What stimulates chemoreceptors

Answer 4

Increased carbon dioxide, decreased oxygen, increased blood acidity

Question 5

Most powerful stimulus driving respiration

Answer 5

Pco2 level
