Where is brachiocephalic veins located?
thorax
The brachiocephalic veins also referred to as the innominate veins, are large venous structures located within the thorax and originate from the union of the subclavian vein with the internal jugular vein. The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest.
What area does the brachiocephalic vein serve?
The brachiocephalic vein, also known as the innominate vein, is a paired vein of the superior mediastinum that drains the venous blood from the head and neck, upper limbs and the upper part of the thorax.
Is brachiocephalic artery oxygenated or deoxygenated?
Oxygenated blood exits the heart through the aorta and reaches the arms through the brachiocephalic trunk and the left and right subclavian arteries that run beneath the collar bones. Continue Scrolling To Read More Below…

Where 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.
Are there two brachiocephalic veins?
The left common carotid, and the left subclavian artery, come directly off the aortic arch. However, there are two brachiocephalic veins.
Is brachiocephalic vein Central?
Central lines terminating in the brachiocephalic trunk or subclavian vein are probably fine to use for most critical care applications (other than, for example, measurement of central venous pressure or mixed venous oxygen saturation).
Does brachiocephalic artery carry oxygenated blood?
Brachiocephalic Artery Function This relatively short artery supplies oxygenated blood to the head, neck and arm regions of the body.
Which region of the heart supplies oxygenated blood to the aorta?
The left ventricle receives oxygenated blood from the left atrium, then sends it on to the aorta. The aorta branches into the systemic arterial network that supplies all of the body.
Where does the brachiocephalic artery bifurcate?
right common carotid artery
The brachiocephalic trunk bifurcates into the right common carotid artery and right subclavian artery posterior to the sternoclavicular joint. It typically has no preterminal branches, but occasionally it can give off a bronchial, thymic, or thyroidea ima artery.
Does the brachiocephalic trunk carry oxygenated blood?
What makes up the brachiocephalic artery?
It is the first branch of the aortic arch, and soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. The left common carotid, and the left subclavian artery, come directly off the aortic arch. However, there are two brachiocephalic veins.
Where is the brachiocephalic artery located in the body?
The brachiocephalic artery is located only on the right side of the body; there is no corresponding artery on the left. The brachiocephalic artery branches into the right subclavian artery and the right common carotid artery.
Where does the brachiocephalic trunk begin and end?
The brachiocephalic trunk, also called the brachiocephalic or innominate artery, is the second branch to arise from the aorta. It courses upwards from the aortic arch through the superior mediastinum, until it reaches the right sternoclavicular joint, where it divides into its final branches.
How is the brachiocephalic trunk related to the vagus nerve?
Anteriorly, the brachiocephalic trunk is related to the left brachiocephalic and right inferior thyroid veins, the right cardiac branches of the vagus nerve, the thymus gland, and the sternohyoid and sternothyroid muscles.
Why is the brachiocephalic trunk called the innominate artery?
It is also known as the innominate artery or the brachiocephalic trunk. The name refers to the fact that blood flows through this very short artery to the arm (brachio) and the head (cephalic). It is an artery, meaning that it is a thick-walled blood vessel that carries blood away from the heart.
