Picture of the Aorta © 2013 WebMD, LLC. All rights reserved. Prev Next 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.

CVS - Coronary arteries 1 The left anterior descending... Coronary arteries 1. The left anterior descending artery is the primary source of blood for the anterior wall of the heart. The circumflex artery supplies the lateral wall. The internal mammary artery supplies the mammary. The right coronary artery supplies the right ventricle and the inferior wall of the heart. 2. Most of the blood flow to coronary arteries is supplied during diastole. 3. Coronary artery disease (CAD) is the leading cause of death in the U.S. (accounts for over 50% of all deaths) 4.

Picture of the Arteries 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.ll rights reserved. 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: 1  The intima, the inner layer lined by a smooth tissue called endothelium.

What is the aorta? The aorta is the largest artery in the body. A normal aorta is 2.5 to 3.5 cm in size, about the same as a garden hose. The aorta delivers oxygenated blood pumped from the heart to the rest of the body. The aorta extends upward from the top of the main pumping chamber of the heart (the left ventricle).

Vertebral artery dissection Vertebral artery dissection (VAD) is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow.

- The arch of the aorta is the second major anatomical region of the aorta; it curves above the heart between the ascending and descending aorta. All of the blood delivered from the heart to the systemic tissues of the body passes through the aorta, making it the largest artery in the human body.s the aorta extends from the heart, it begins as the ascending aorta before turning 180 degrees towards the body’s left side in the aortic arch. From the arch the aorta passes posterior to the heart and descends through the thorax and abdomen as the descending aorta....

What is the Aortic Root? From the descending aorta, the blood travels from various arteries to the rest of the body. The aortic root is the first section of the aorta, which is the largest artery in the human body. It is located within the chest cavity, behind the left half of the sternum. The root of the aorta begins at the aortic annulus, where the right and left coronary artery connect to the aorta, and ends at the limit of pericardium.
