Definition: The term "Aorta" refers to a vessel that carries blood from the heart to the rest of the body's organs, including the brain, lungs, heart, and digestive tract. Aorta is typically described as being an oval-shaped structure with four main branches: left, right, superior, and inferior (the latter two are known as "superior" and "inferior"). The word "Aortography" means "a diagram or map of the anatomy of aorta." In this context, it refers to a detailed visual representation showing various organs within the aortic arch, including: 1. Heart: This is the largest organ in the body, and its walls are divided into three main chambers called the left ventricle (also known as a "right heart"), the right atrium and the left atrium. 2. Vessels: Aorta contains many small arteries and veins. The major arteries include the great vessels of the head and neck (such as the common, subclavian, and femoral arteries) and smaller ones such as the left anterior, middle, and posterior aeries. 3. Bladder: The bladder is an organ that stores urine and produces feces through its urethra. In summary, Aorta represents the heart's valves, vessels, walls, and organs surrounding it, making it essential for blood circulation within our bodies.
