Answer 2

There are twenty main arteries, unfortunately, I do not know them all, but I can name a few to get the ball rolling:
Carotid artery: runs up both sides of the neck and is the artery felt when taking a pulse from the neck, delivers blood to the brain.
Femoral: runs through the middle of the thigh on both legs, delivers blood to the lower extremities above the elbow.
Brachial: runs from the anterior of the shoulder to the elbow, delivers blood to the upper extremities.
Radial and Ulnar: stems off of the brachial and goes around the radius and ulna respectively, feeds blood to the flangies and lower extremites below the elbow.
