In human anatomy, the carotid artery refers to a number of major arteries in the head and neck. Carotid artery can mean: Common carotid artery External carotid artery Internal carotid artery There are two carotid arteries, one on the left and one on the right. From their origins and for about half their length, the carotid arteries are known as common carotid arteries. The left carotid arises from the arch of the aorta, while the right carotid arises as one of the branc ...

The vertebral arteries are branches of the subclavian arteries. They arise, one on each side of the body, then enter deep to the transverse process of the level of the 6th cervical vertebrae (C6). It then proceeds superiorly, under the transverse process of each cervical vertebra until C1 where it enters the skull via the foramen magnum. Inside the skull, the two vertebral arteries join up to form the basilar artery at the base of the medulla oblongata. The basilar artery is the main blood supply to the brainstem and connects to the Circle of Willis to potentially supply the rest of t ...

In human anatomy, the cephalic vein is a superficial vein of the upper limb. It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle. Superiorly the cephalic vein passes between the deltoid and pectoralis major muscles and through the deltopectoral triangle, where it empties into the ...

The superior and inferior venae cavae are the veins that return the blood from the body into the heart. They both empty into the right atrium. The inferior vena cava travels up alongside the abdominal aorta with blood from the lower part of the body. The superior vena cava is above the heart, and forms from a convergence of the left and right brachiocephalic veins that contain blood from the head and the arms. The vena cava carries blood from the body to the ri ...

The vein of Galen (VG), also known as the great cerebral vein, is one of the large blood vessels in the skull draining the cerebrum (brain). It is prone to congenital defects, such as vein of Galen aneurysmal malformations (VGAM) and vein of Galen aneurysmal dilation (VGAD). It is named after its discoverer, the Greek physician Galen.

The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspect of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist. Along its course, it is accompanied by a similarly named vein or veins, the ulnar vein or ulnar veins.

Umbilical arteries carry deoxygenated blood from the fetus to the placenta in the umbilical cord. There are usually two umbilical arteries present together with one umbilical vein in the cord. Occasionally, there is only the one single umbilical artery present in the cord. Babies with this finding are usually smaller than normal and have a higher likelihood of having other congenital abnormalities. The umbilical arteries are actually the latter of the internal iliac arteries that supply the hind limbs with blood in the f ...

The coronary circulation consists of the blood vessels that supply blood to, and remove blood from, the heart. The vessels that supply blood high in oxygen to the heart are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart are known as cardiac veins. The coronary arteries that run on the surface of the heart are called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart mu ...

The celiac artery, also known as the celiac trunk, is the first major branch of the abdominal aorta. It supplies oxygenated blood to the liver, stomach, spleen, duodenum and the pancreas. Shortly after its formation, the celiac artery divides into the: left gastric artery, common hepatic artery and splenic artery. The celiac artery is the only major artery nourishing the abdominal digestive organs that does not have a similarly named vein (i.e. the superior mesenteric a ...

In human anatomy, the basilar artery is one of the arteries that supplies the brain with oxygen-rich blood. It arises from the confluence of the two vertebral arteries at the level of the medulla oblongata. It ascends in the central gutter (sulcus basilaris) inferior to the pons and divides into the two posterior cerebral arteries. From the basilar artery arise branches for the supply of the cerebellum (largely via the anterior inferior cerebellar artery), as ...

The brachial artery is the major blood vessel of the upper arm. It is a continuation of the axillary artery and it originates from the lower margin of teres major muscle and continues down the arm, until it reaches the cubital fossa at the elbow. It then ends by dividing into the radial and ulnar arteries which run down the forearm. The brachial artery has smaller branches along it. These supply the muscles of the upper arm, suc ...

In human anatomy, the basilic vein is a superficial vein of the upper limb. It communicates with the cephalic vein via the median cubital vein at the elbow and drains into the axillary vein. It is a superficial vein that drains the back of the hand and forearm. It communicates with the cephalic vein via the median cubital vein at the elbow, then runs superficially medial to the biceps brachii muscle and perforates the deep fascia about midway up the arm where it runs medial to the brachial artery. It joins the brachial vein and becomes the axillary ...

Bronchial Artery The bronchial arteries supply nutrients and oxygen to the root of the lungs, the supporting tissues of the lungs, and the visceral pleura of the lungs. The right and left bronchial arteries supply the right and left lungs respectively. It is a common mistake to believe that the lungs take their only blood supply from the right side of the heart, which is the side of the heart that pumps blood to the lungs to be oxygenated. The bronchial arteries instead take their blood supply from the left side of the heart, w ...

The exact anatomy of the myocardial blood supply varies considerably from person to person. A full evaluation of the coronary arteries requires cardiac catheterization. In general there are two main coronary arteres, the left and right. Both of these arteries originate from the beginning (root) of the aorta, immediately above the aortic valve. As discussed below, the left coronary artery originates from the left aortic sinus, while the right coronary artery originates from the right aortic sinus. See also:

The papillary muscles tether the mitral valve (the valve between the left atrium and the left ventricle) and the tricuspid valve (the valve between the right atrium and the right ventricle) to the wall of the heart. If the papillary muscles are not functioning properly, the mitral valve leaks during contraction of the left ventricule. This causes some of the blood to travel "in reverse", from the left ventricle to the left atrium, instead of forward to the aorta and the rest of the bo ...
