A large artery within the abdomen that arises from an arterial vessel called the celiac trunk, which emerges from the aorta. The splenic artery supplies blood not only to the spleen, but also to the esophagus, stomach, duodenum, liver, and pancreas.

One of the two vessels which are formed as terminal branches of the pulmonary trunk and convey un-aerated blood to the lungs. The two pulmonary arteries differ in length and anatomy. The right pulmonary artery is the longer of the two. It passes transversely across the midline in the upper chest and passes below the aortic…

The ophthalmic artery supplies blood to the eye and adjacent structures of face. It arises from the internal carotid artery that courses up deep within the front of the neck.

An artery that distributes blood to the liver, pancreas and gallbladder as well as to the stomach and duodenal portion of the small intestine.

The continuation of the external iliac artery after it passes under the inguinal ligament. The femoral arteries supply oxygenated blood from the heart to the lower extremities.

The blood vessel that carries blood into the eye and supplies nutrition to the retina. The counterpart to the central retinal artery is the central retinal vein, the vessel that carries blood away from the retina.

Either of the two key arteries located in the front of the neck, through which blood from the heart goes to the brain. The right and left common carotid arteries are located on each side of the neck.

The artery that runs from the shoulder down to the elbow.

A sudden constriction of a coronary artery that deprives the heart muscle of blood and oxygen. This can cause a type of sudden chest pain referred to as variant angina or Prinzmetal angina. Coronary artery spasm can be triggered by emotional stress, medicines, street drugs (particularly cocaine), and exposure to extreme cold. Treatments include the use of beta-blocker medications and, classically, nitroglycerin to allow the coronary arteries to open.
