aortic arch
The aortic arch is a curved section of the aorta, the largest blood vessel in the body. It connects the ascending aorta, which carries blood away from the heart, to the descending aorta. The arch is crucial because it gives rise to major arteries that supply blood to the arms, head, and neck. Its shape allows for the efficient distribution of oxygen-rich blood throughout the upper body. Understanding the aortic arch helps in comprehending cardiovascular health, as issues in this area can lead to serious health problems.
