Does the brachiocephalic artery supply the brain?
The brachiocephalic trunk, also called the brachiocephalic or innominate artery, is the second branch to arise from the aorta. The brachiocephalic trunk gives off the right subclavian artery, supplying the right upper limb; and the right common carotid artery, supplying the right side of the brain, head and neck.
Where does blood go from the brachiocephalic artery?
There is no brachiocephalic artery for the left side of the body. The left common carotid, and the left subclavian artery, come directly off the aortic arch. However, there are two brachiocephalic veins….Brachiocephalic artery.

What does the brachiocephalic artery supply blood to?
The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.
Is the brachiocephalic artery oxygenated or deoxygenated?
Brachiocephalic Artery Function This relatively short artery supplies oxygenated blood to the head, neck and arm regions of the body.
What does brachiocephalic branch into?
The normal aortic arch branches into three, the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. After a short superior course, the brachiocephalic artery then divides into the right subclavian and right common carotid arteries.
What is the function of the brachiocephalic vein?
The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest. These vessels are a vital component of the human circulatory system, aiding in drainage of deoxygenated blood from the head and upper limbs.

What are the 3 main cerebral arteries?
The three main arteries are the:
- Anterior cerebral artery (ACA)
- Middle cerebral artery (MCA)
- Posterior cerebral artery (PCA)
Which artery supplies the anterior circulation of the brain?
internal carotid artery
The major branches that arise from the internal carotid artery—the anterior and middle cerebral arteries—form the anterior circulation that supplies the forebrain (Figure 1.20B). These arteries also originate from the circle of Willis.
