So just like we have a left subclavian artery, we also have a right subclavian arteries that extends into the right shoulder and into the right arm and the right hand of our body. Now in the same way that we have this splitting taking place and we form our left vertebral artery, we also form the right vertebral arteries. So this is the right vertebral artery right here. So we have symmetry taking place. Now the subclavian artery, the common carotid artery, this vertebral artery all bring our oxygenated and nutrient filled blood to the organs and tissues found in the upper portion of our body. In the head portion, the neck region, the shoulders, as well as our arms and the coronary arteries bring our blood to the heart of our body.
