Hyperventilation helps to compensate for lactic acidosis

Hyperventilation begins as soon as lactate production increases

Hyperventilation facilitates diffusion of oxygen

Hyperventilation is facilitated by increased pulmonary capillary blood flow

Hyperventilation occurs when tidal volume and rate begin to increase

Explanation / Answer

1.False( Lactic acidosis is the cause of exercise-induced Hyper Ventilation).

2.True ( hyperventilation begins after lactate production increases)

3.False.(hyperventilation results in diffusion and excess amounts of carbon dioxide)

4.False (Increased pulmonary capillary blood flow is called external respiration,wich involves diffusion of oxygen to blood stream whereas in hyperventilation carbondioxie production is in Excess).

5.True (Tidal volume of pco2 increase can cause hyperventilation).
