Q

What do the peripheral chemosensitive receptors mostly monitor?

A

O2 partial pressure in arterial blood

1
Q

What is the primary controller of the rate and depth of breathing?

A

Pneumotaxic center

2
Q

What do central chemosensitive receptors mostly monitor?

A

CO2 levels via pH of blood

3
Q

How does the pneumotaxic center control breathing?

A

It controls the “shut-off” point of the inspiratory ramp signal during normal breathing

4
Q

What is the ventral respiratory group primarily responsible for?

A

Forced expiration

5
Q

What is Cheyne-Stokes breathing?

A

Repeated breathing cycle of apnea replaced by increasingly rapid/deep breathing
Often associated with cardiac arrest

6
Q

What are juxtaglomerular receptors sensitive to?

A

Pulmonary edema (such as in congestive heart failure)

7
Q

What is the Hering-Breuer reflex?

A

It responds to excessive stretching of the lung
