Sherell has damaged her phrenic nerve after diving head-first into a shallow lake. Predict the effect on her pattern of ventilation

What will be an ideal response?


The phrenic nerve supplies the diaphragm with nerve impulses that promote inspiration. Without a viable connection to the ventral respiratory group (VRG) in the medulla, the rate of ventilation cannot be controlled. Sherell's diaphragm may not contract when needed and the rate of pulmonary ventilation will decrease.
