Select from the dropdown lists to complete the text.

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