If the ventral respiratory group (VRG) of neurons was destroyed: If the ventral respiratory group (VRG) of neurons was destroyed: breathing would stop. tidal volumes would increase. alveolar ventilation would increase. pulmonary ventilation would increase rapidly.

Breathing would stop.

Explanation:

Respiratory centre is the group of neuron located in the brain mainly in the pons and medulla. In the medulla, there is two types of neuron group: the dorsal and the ventral group of neurons.

The ventral group of neuron in medulla controls the muscles involved in the inspiration and expiration of the lungs.

Since the inspiration and expiration are associated with the breathing mechanism therefore if the ventral neurons will be destroyed then the breathing would stop.

Thus, the selected option is correct.
