What is the primary blood vessel that supplies blood to the head, face, and neck?

• A. Jugular vein
• B. Subclavian artery
• C. Carotid artery
• D. Aorta

Answer: (C)

The carotid artery is the primary blood vessel responsible for supplying oxygenated blood to the head, face, and neck. This artery branches into two main sections: the internal carotid artery, which supplies blood to the brain, and the external carotid artery, which supplies blood to the face and neck structures. Understanding the role of the carotid artery is crucial for various reasons, including its relevance in medical procedures and in evaluating the risk of cardiovascular health issues related to these areas of the body. This artery's significance is highlighted in first aid scenarios, where understanding its location and function can be vital in providing assistance in emergency situations. The other choices represent vessels that have different roles: the jugular vein primarily drains blood from the head and neck back to the heart, the subclavian artery supplies blood to the arms and parts of the chest, and the aorta is the main artery that carries blood from the heart to the rest of the body.
