Arteries of the Neck and Head
...  and neck allow blood to circulate properly on the upper parts of the systematic loop. The circulation originates from the aortic arch and the arteries supplying the blood, including the left common carotid artery, the brachiocephalic artery and the left subclavian artery. Blood goes from the head and neck through the jugular vein and the subclavian vein. The brachiocephalic artery or trunk is  ...

Aortic Arch
...  the Arch of Aorta. It is a bow-like structure. It is the curving portion between the ascending aorta and the descending aorta. This structure gives rise to the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. The plura and anterior margins of the lungs cover the arch of the aorta. The remains of the thymus also contribute to the covering of the arch of the  ...

Blood Supply to the Brain
...  reach the brain? There are four vessels through which the arterial blood passes going to the brain. Each of these four vessels is actually in sets of paired arteries – one set of internal carotid arteries and a pair of vertebral arteries. These eventually converge into one unified vessel found near the pituitary gland, which is located in the interior surface of the brain. The  ...

External Carotid Arteries
...  head and neck houses the common carotid artery. There are two common carotid arteries, and these arteries supply oxygenated blood to the head and neck. The common carotid artery bifurcates into the external carotid artery and the internal carotid artery. The external carotid artery supplies blood to the exterior of the head, the face and the greater part of the neck. On the other hand, the  ...

Veins To The Head And Neck
...  sinuses. These venous sinuses facilitate the reception of the blood coming from the opthalmic, cerebellar and meningeal veins. The internal jugular veins run down the vagus nerve and the common carotid artery, situated near the inferior regions of the neck. The carotid sheath protects all the veins located beneath the sternocleidomastoid muscles . The brachiocephalic vein is formed by the  ...

Thyroid Gland
...  The thyroid is the biggest of all the endocrine glands, specifically found beneath the larynx. This organ’s high denmand for vascular support is satisfied by the two branches of the external carotid arteries, and the inferior thyroid branches of the subclavian arteries. Superior and middle thyroid veins provide venous drainage to the thyroid. The veins travel from the internal jugular  ...
