- CFuck all
- DReturns to normal* immediately
- ERemains in exercise-state for a while
- FFuck all
- GRemains in exercise-state for a while

3As exercise intensity increases…
TPR [blank_start]__________[blank_end];
MAP [blank_start]__________[blank_end];- AFalls
- BFalls slightly
- CFalls dramatically
- DRises
- ERises slightly
- FRises dramatically
4During exercise, the motor cortex sends signals to:

- BBrainstem
- CSkeletal muscle
- DPons
- EHippocampus
5Which of the following move the curve to the right?

- AIncreased H+ concentration
- BIncreased CO2 concentration
- CIncreased temperature
- DDecreased pH
- EDecreased H+ concentration
- FDecreased CO2 concentration

6In 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);- AIncreased
- BDecreased
- CIncreased
- DDecreased
- EIncreased
- FDecreased
