Explain regulation of respiration in points
Answers
The ventral respiratory group controls voluntary forced exhalation and acts to increase the force of inspiration.
The dorsal respiratory group (nucleus tractus solitarius) controls mostly inspiratory movements and their timing.
Ventilatory rate (minute volume) is tightly controlled and determined primarily by blood levels of carbon dioxide as determined by metabolic rate.
Chemoreceptors can detect changes in blood pH that require changes in involuntary respiration to correct.The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing.
The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing.
respiratory control centers: The medulla which sends signals to the muscles involved in breathing, and the pons which controls the rate of breathing.
chemorecepters: These are receptors in the medulla and in the aortic and carotid bodies of the blood vessels that detect changes in blood pH and signal the medulla to correct those changes.
