Define the concept of ventilation, Biology

Assignment Help:

Which of the following are true for ventilation?

A. The problems with ventilation induced by injection of curare occur because of the drug's direct action on nicotinic ACh Receptors (nAChRs) in the sarcoplasmic reticulum membranes of the respiratory muscles (the diaphragm and the rib-cage muscles).

B. An increase in the hydrogen ion concentration in the interstitial spaces of the brain stem leads to a decrease in the duration of the respiratory cycle (duration of respiratory cycle equals duration of inspiration plus duration of expiration).

C. When the pressure within the alveoli is greater than atmospheric pressure, there will be inspiration of air into the lungs.
