What three arteries branch off from the aorta (at the aortic arch)? Where do they supply blood to?

Ok so there's the brachiocephalic artery, which supplies blood to the right arm and the brain(it bifurcates into the right subclavian and right common carotid arteries right?)Then there's the left common carotid artery( also supplies blood to the brain) and the left subclavian artery (supplies blood to the left arm).

Correct, for the most part. I wouldn't say that the right common carotid supplies blood for just the brain. I would include that it supplies blood to the right portion of the head and neck. Also remember to hide your answer.

Ok thanks! I guess it's my turn...

Explain what causes the plateau phase in cardiac muscle contraction.

I doubt this is right... (Click to Show Hidden Text)

A balanced influx of calcium and outflow of potassium causes the plateau phase.

Yes that's correct! I would also add that it prolongs the action potential duration within the cardiac muscle. Your turn.

Sorry, this is random.

Where do you guys study because you seem to know lots of material?

Probably should be on the Study Events forum, but personally I use a lot of Wikipedia.
