Introduction

The human body is composed of many different organs, systems and tissues that all work together to maintain proper functioning. The thorax and neck contain a number of important arteries that are involved in the transport of oxygenated blood and other nutrients throughout the body. In this article, we will review the anatomy of the arteries of the thorax and neck and discuss their importance to human health.

Anatomy of the Arteries of the Thorax and Neck

The thoracic and neck arteries are part of the systemic circulation, which supplies oxygenated blood from the heart to the rest of the body. The major arteries of the thorax and neck include the aorta, brachiocephalic trunk, left common carotid artery, left subclavian artery, left vertebral artery, and right common carotid artery.

The aorta is the largest artery in the body and is responsible for transporting oxygenated blood from the left ventricle of the heart to the entire body. It is divided into the ascending aorta, aortic arch and descending aorta. The aortic arch branches into the brachiocephalic trunk, left common carotid artery and left subclavian artery. The brachiocephalic trunk supplies oxygenated blood to the right arm and right side of the head. The left common carotid artery supplies oxygenated blood to the left side of the head and the left subclavian artery supplies oxygenated blood to the left arm.

The left vertebral artery and right common carotid artery are responsible for supplying oxygenated blood to the neck and head. The left vertebral artery arises from the subclavian artery and ascends through the vertebral canal to supply the posterior part of the brain. The right common carotid artery supplies oxygenated blood to the right side of the head and neck.

Clinical Considerations

The thorax and neck arteries are important for supplying oxygenated blood and other nutrients to the tissues of the body. Disruption of blood flow to these areas can lead to tissue death, stroke, aneurysms, and other serious health conditions.

It is important for healthcare providers to assess the patency and integrity of these arteries during physical examinations. Various imaging modalities such as X-ray, CT scan, and MRI can be used to assess the anatomy and blood flow of these vessels.

In cases of vascular trauma, such as a carotid artery dissection, thrombosis or embolism, medical interventions such as drug therapy, stenting, or surgery may be needed to restore normal blood flow.

Conclusion

The thorax and neck contain a number of important arteries that are responsible for supplying oxygenated blood and other nutrients to the tissues of the body. It is important for healthcare providers to assess the patency and integrity of these arteries during physical examinations, and to intervene quickly in cases of vascular trauma. By understanding the anatomy and clinical importance of the thorax and neck arteries, healthcare providers can ensure that their patients receive the best possible care.
