Aorta: The largest artery in the body, the aorta arises from the left ventricle of the heart, goes up (ascends) a little ways, bends over (arches), then goes down (descends) through the chest and through the abdomen to where ends by dividing into two arteries called the common iliac arteries that go to the legs.  The aorta is the central conduit from the heart to the body. Three great vessels arise from the top of the aortic arch. On the right is the innominate artery, which divides into the right subclavian artery and the right common carotid artery for the head and neck. The aorta has a thick wall, with three layers of muscle that allow the blood vessel to withstand the high pressure that is generated when the heart pumps blood to the body. The three layers are the tunica intima, tunica media, and the tunic adventitia. © 2013 WebMD, LLC. All rights reserved. The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. The aorta is a tube about a foot long and just over an inch in diameter. The femoral artery is the main artery that provides oxygenated blood to the tissues of the leg. It passes through the deep tissues of the femoral (or thigh) region of the leg parallel to the femur. The common femoral artery is the largest artery found in the femoral region of the body.  Overview. The aorta is the main artery that carries blood from the heart to the rest of the body. The aorta comes out from the left ventricle of the heart and travels through the chest and abdomen. A thoracic aortic aneurysm (TAA) is an abnormal bulge or ballooning in the wall of the aortic artery running through the thorax (chest). One in four aortic aneurysms are TAAs. An aneurysm that occurs in the part of the aorta running through the abdomen is an abdominal aortic aneurysm (AAA) . Three in four aortic aneurysms are AAAs. An aneurysm that grows and becomes large enough can burst, causing dangerous, often fatal, bleeding inside the body. 1. Aorta is the main blood vessel in the human heart. It branches of from the heart of the living beings and further carries on the function of transferring the oxygenated blood to the other vessels of the body and these vessels then take the blood which has been oxygenated to the parts of the body. 1 Aorta is the main blood vessel in the human heart. 2  The abdominal aorta is the largest blood vessel in the body and is responsible for blood flow to all vital organs in your body. It is the main artery stemming from the heart running through your chest and abdomen, located above the belly button in the middle and upper abdomen.  This article uses anatomical terminology; for an overview, see anatomical terminology. The aorta (/eɪˈɔrtə/) is the main artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.  1 Carotid artery: runs up both sides of the neck and is the artery felt when taking a pulse from the neck, delivers blood to the brain. 2  Femoral: runs through the middle of the thigh on both legs, delivers blood to the lower extremities above the elbow.  The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries. The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers:
