PHSI3011 04-2 Cardio- and resp- regulation during exercise

Effect of exercise on the following things:
Ventilation rate Jumps immediately Remains steady Jumps, but lags Drops immediately Drops, but lags( Jumps immediately, Remains steady, Jumps, but lags, Drops immediately, Drops, but lags );
Arterial blood gases and pH Remain steady Jump immediately Jump, but lags Drop immediately Drop, but lags( Remain steady, Jump immediately, Jump, but lags, Drop immediately, Drop, but lags );
Oxygen supply to existing cells Jumps, but lags Remains steady Jumps immediately Drops, but lags Drops immediately( Jumps, but lags, Remains steady, Jumps immediately, Drops, but lags, Drops immediately );

At the end of exercising, what happens to each of the following parameters:
HR Remains in exercise-state for a while Returns to normal* immediately Fuck all( Remains in exercise-state for a while, Returns to normal* immediately, Fuck all );
MAP Returns to normal* immediately Remains in exercise-state for a while Fuck all( Returns to normal* immediately, Remains in exercise-state for a while, Fuck all );
TV Remains in exercise-state for a while Returns to normal* immediately Fuck all( Remains in exercise-state for a while, Returns to normal* immediately, Fuck all );

In skeletal muscle during maximal exercise:
Blood flow is Increased Decreased( Increased, Decreased ) ~3X ~6X ~20X ~30X ~60X ~180X ~2X ~40X ~120X( ~3X, ~6X, ~20X, ~30X, ~60X, ~180X, ~2X, ~40X, ~120X ) (compared to rest);
Oxygen extraction fraction is Increased Decreased( Increased, Decreased ) ~2X ~3X ~6X ~20X ~30X ~40X ~60X ~120X ~180X( ~2X, ~3X, ~6X, ~20X, ~30X, ~40X, ~60X, ~120X, ~180X ) (compared to rest);
…therefore Oxygen consumption is Increased Decreased( Increased, Decreased ) ~2X ~3X ~6X ~20X ~30X ~40X ~60X ~120X ~180X( ~2X, ~3X, ~6X, ~20X, ~30X, ~40X, ~60X, ~120X, ~180X ) (compared to rest);
