How is respiration controlled by the brain?
The pacemaker, or medullary respiratory control centre, gets three types of input.
- The control centre incorporates these impulses.
- The respiratory centre's output is then changed in timing or strength, resulting in alterations in rate and tidal volume.
- Chemical feedback, mechanical feedback, and information from higher cortical areas are the three types of feedback.
The average person can regulate Pao2, Paco2, and pH within limited ranges.
- The respiratory centre takes information from both peripheral and central chemoreceptors to achieve this degree of control.
- The primary peripheral receptors are situated in the carotid bodies found at each common carotid artery bifurcation.
- Similar structures exist in the aorta, although nothing is known about these aortic entities.
