A: The function of the arteries is to carry oxygenated blood to organs and cells in the body. Because of this, arterial blood has a bright red color and flows away from the heart. Arterial walls have three layers. The outer layer is elastic connective tissue, and the middle layer is made out of muscle.
ANSWER: Arteries usually carry oxygenated blood from heart to all the parts of the body whereas a coronary artery carries oxygenated blood and supplies it to the heart muscle-myocardium (for its functioning!) and that's where usually angina results as a result of artery thickening.
