The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body. Thoracoabdominal Aorta (Descending and Abdominal Aorta) Cleveland Clinic is a non-profit academic medical center. The aorta is the main artery that carries blood away from your heart to the rest of your body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.

The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body. An aortic aneurysm is an abnormal enlargement or bulging of the wall of the aorta.

An aneurysm can occur ueart in the vascular tree. Once and aneurysm is diagnosed, treatment may be needed, depending on the size of the aneurysm. Ruptured aneurysms require emergency surgery to stop the bleeding. The aorta has many layers. Aortic dissection is a tear that develops in the inner layer of the aorta, causing blood to flow between the layers.

The layers then separate, interrupting the blood flow and possibly causing the arterial wall to burst. Aortic dissection can be a life-threatening emergency, in some situations requiring emergency surgery to repair or replace the damaged segment of the aorta.

What Is The Function Of The Descending Aorta In The Heart?

Sep 11,  · The aortais the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heartpumps bloodfrom the left ventricle into the aorta. The aorta runs right down the middle of your body. But it doesn’t take a completely straight path. It starts at the aortic valve, a special flap that connects the heart to the aorta. The aortic valve’s job is to keep blood from flowing backwards after it’s left the heart. Jun 24,  · The aorta rises from the left ventricle of the heart, forms an arch, then extends down to the abdomen where it branches off into two smaller arteries. Several arteries extend from the aorta to deliver blood to the various regions of the body. Function of the Aorta The aorta carries and distributes oxygen-rich blood to all arteries.

During the functioning of the heart, it pumps the blood from the left ventricle that passes through the aortic valve and reaches the aorta. For every heartbeat, the aortic valve allows passage of blood in one direction when the three leaflets present in it open and close. Coming to the dimensions the aorta measures one foot in length and approximately an inch in diameter. Aorta consists of the following four sections:.

Intima: The intima is the inner layer, which is smooth for it provides the support for the free flow of the blood. The Media: The media is the medium layer, which consists of elastic fibers and muscle.

The layer expands and contracts for every heartbeat. Adventitia: The outer layer is the adventitia, which provides structural support. The starting point of the descending aorta is at the aortic arch. It loops across the heart to begin its descending journey. Additionally, the descending aorta consists of two segments — abdominal aorta and the thoracic aorta. The thoracic aorta or the descending aorta lies between the diaphragm muscle and the aorta.

The descending aorta, which begins at the aortic arch, branches out from the heart from the left vertebrae. Due to the descending action, it spirals across the vertebrae and stops the journey at the front. The artery measures 2. Intercostal arteries exist in nine pairs. Because of the branching from the left vertebrae, the branches of the artery are long in the right side when compared with that of the left.

The several branches of the arteries across the descending aorta help in supply blood to lungs, the chest region, esophagus, mammary glands, and the ribs. An increase in blood pressure along with abnormal cholesterol level is responsible for the buildup of plaques that make it difficult for passage of the blood pumped through the heart. Due to this, an individual experiences heart stroke. Along with that, when there is a weakness developed in the aortic wall, the blood flow causes to create a balloon.

The medical term for such situation is an aortic aneurysm. The aneurysms grow over a period at a slow pace. It is difficult to find its presence because it does not display any signs of early symptoms.

However, when ruptured, it poses a threat to the life. Other health effects include aortic dissection, aortic insufficiency, aortic stenosis, coarctation of the aorta, aortitis, and bicuspid aortic valve. Detecting these effects in early stages will be helpful in overcoming critical situations.

Screening for the presence of any of the conditions includes MRI scan , CT scan , angiography, x-ray , abdominal ultrasound , and transthoracic echocardiogram.
