receptors involved in regulation of pulminary ventilation

Question 1

what do chemoreceptors do and where are they located

Answer 1

located in the carotid artery and aortic arch they detect increase in the plasma concentration of carbon dioxide and in lactic acid production, they send impulses ron the inspiratory system to increase ventilation until blood acidity has returned to normal

Question 2

how’s does the respiratory centre respond to the impulse from the chemoreceptors

Answer 2

sends impulses down the phrenic nerve to stimulate more inspiratory muscles(that are also expiratory naturally)- sternocleidomastoid, scalenes, pectoralis minor. the rate and depth of breathing increase

Question 3

what do proprioreceptors do

Answer 3

detect an increase in muscle movement and feedback to the respiratory centre to increase breathing during exercise

Question 4

what do baroreceptors do

Answer 4

detect an increase in blood pressure in the aorta and carotid artery, resulting in increased breathing rate
