Structure
The aorta is the largest artery in the body to which all other major arteries are connected.It is a big tube-like structure, usually about 1 inch wide in diameter, although its size varies proportionally to the height and weight of the person. The aorta is widest at the point where it connects to the heart's left ventricle through the aortic valve; then, it gets progressively narrower as it descends into the abdomen. The aorta is divided into four parts: 1. Ascending aorta: This is the first...
Location
The aorta is located at different parts of the body. It starts at the heart’s left ventricle, goes through the chest, and ends at the lower abdomen.
Anatomical Variations
For people that have dextrocardia (a condition where the heart is located on the right side of the body), the aorta is usually on the right side instead of on the left side.The same applies to people who have a condition called situs invertus, where all the organs are on the opposite side of where they usually are—like a mirror image. There is a birth defect known as coarctation of the aorta, in which a part of the aorta is significantly narrower than it ordinarily should be. The narrowing is...
The main function of the aorta is to supply blood to almost all the major organs in the body through the smaller arteries that arise from it. Broken down, the function of the different parts of the aorta are: 1. Ascending aorta:This part of the aorta connects to the aortic valve and it collects oxygenated blood from the left ventricle of the heart....
There are several conditions with serious complications that center around or affect the aorta. Aortic aneurysm: An aortic aneurysmis bulge in the wall of the aorta. It is a serious condition because if the aorta ruptures at that spot, it can lead to life-threatening severe internal bleeding and other serious complications. Aortic atherosclerosis:T...

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).
Apr 21, 2024 · The aorta is the largest artery in the body, receiving the cardiac output from the left ventricle and supplying the body with oxygenated blood. It has four sections: the ascending aorta, the aortic arch, the thoracic aorta and the abdominal aorta, each with different branches and clinical relevance.

Arteries, a critical part of your cardiovascular system, are blood vessels that distribute oxygen-rich blood to your entire body. These tube-like vessels and the muscles inside them ensure your organs and tissues have the oxygen and nutrients they need to function. A condition called atherosclerosis can slow down blood flow through your arteries.
