100
Which lobe is represented by A?
Frontal lobe
100
If I start exercising, what will happen to my blood flow right away?
What will happen after I stop?
Blood flow will increase because heart rate increases.
Blood flow will slow as heart rate slows

Which lobe is represented by B?
Parietal Lobe
200
What effect does increased plaque in an artery have on blood flow?
decreases flow (increased resistance)
200
What does a phagocyte do?
Engulf (eat) pathogens
200

300
Which lobe is represented by C?
Occipital lobe
300
Vasoconstriction (narrowing of arteries) has what effect on blood flow?
Decreases blood flow
300
What is the way we can prevent infection with a pathogen artificially?
Vaccines
300
What is it called when a wound becomes red and raised?
inflammation

400
Which lobe is represented by D?
Temporal lobe

How are blood flow and blood pressure related? What kind of flow causes high vs low pressure?
Low flow leads to high pressure. High flow leads to lower pressure.
