The aorta (/ eɪ ˈ ɔːr t ə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries).The aorta distributes oxygenated blood to all parts of the ...
What is the anatomy of the aorta? The aorta has many sections, including the: Aortic root: Section that attaches to the heart. This is the widest part of the aorta. Aortic valve: Three flaps of tissue (leaflets) that snap open and shut to release oxygen-rich blood from the heart. Ascending aorta: Upward curve that occurs shortly after the aorta leaves the heart.
The aorta is the largest blood vessel in the body, carrying oxygen-rich blood from the heart to every organ and tissue. It begins at the left ventricle, extends upward through the chest to form an arch, and continues downward, eventually branching into the iliac arteries just above the pelvis. Divided into four sections—the aortic root, ascending aorta, aortic arch, and descending aorta—it ...
The aorta is the largest blood vessel in the body. Although your aorta is a tough, durable workhorse, sometimes its walls can weaken and bulge in what is called an aortic aneurysm. This could ...
Learn about the aorta, the main artery that carries blood from your heart to the rest of your body. Find out what an aortic aneurysm is, how to recognize the symptoms and how to treat it.
Maybe a warning: A tortuous aorta is one that is not straight( the normal condition ) but does not contain and aneurysm. This may occur normally in older people or those with long standing hypertension. It may also occur in younger people who have abnormal composition of their artery walls. In this circumstance it may be a warning of increased ...
The aorta is the main artery responsible for transporting oxygenated blood out of the heart and to the rest of the body. It consists of the ascending aorta, the aortic arch, and descending aorta.
Aorta (aorta) The aorta is the first segment of the systemic arterial circulation, originating directly from the left ventricle of the heart.It is the largest artery in the body consisting of three parts that each has its special characteristics, most notably in their direction and orientation.
The aorta is the first and largest artery in the body. It is responsible for transporting nutrient-rich blood to the systemic circulation following ejection from the left ventricle of the heart. The aorta extends from the aortic valve of the left ventricle to the proximal iliac bifurcation at the L4 vertebral level. The vessel can be divided into various segments depending on course and location.
The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries. The aorta classified as a large elastic artery, and more information on its internal structure can be found here.
