Regulation of Respiration Flashcards
What mostly monitors oxygen partial pressure in arterial blood?
The peripheral chemosensitive receptors (carotid and aortic receptors) that are involved in controlling rate of respiration
What is the primary controller of the rate and depth of breathing?
The pneumotaxic center
What mostly monitors carbon dioxide levels via pH?
Central chemosensitive receptors (located in the brainstem) that are involved in controlling rate of respiration
What controls the “switch-off” point of the inspiratory ramp signal?
The pneumotaxic center
What is primarily responsible for establishing the ramp signal during normal breathing?
The dorsal respiratory group
What is primarily responsible for forced expiration?
The ventral respiratory group
A repeated breathing cycle consisting of a period of apnea replaced by a period of increasingly rapid and deep breathing is referred to as what? What is it often associated with?
Cheyne-Stokes breathing; it is often associated with cardiac arrest.
What are sensitive to pulmonary edema such as occurs in congestive heart failure?
J (juxtaglomerular) receptors (C fibers)
What is the response to excessive stretching of the lung?
The Hering-Breuer reflex
