Question 6
Question
In skeletal muscle during maximal exercise:
Blood flow is [blank_start]__________[blank_end] [blank_start]__________[blank_end] (compared to rest);
Oxygen extraction fraction is [blank_start]__________[blank_end] [blank_start]__________[blank_end] (compared to rest);
…therefore Oxygen consumption is [blank_start]__________[blank_end] [blank_start]__________[blank_end] (compared to rest);
