"descending aorta" 的定义和意义

What is "descending aorta"?

The descending aorta is a vital component of the human cardiovascular system that carries oxygen-rich blood from the heart to the lower body. It is the section of the aorta that extends from the arch of the aorta, located near the heart, down to the abdominal region. The descending aorta supplies oxygenated blood to the organs, tissues, and muscles of the abdomen, pelvis, and lower extremities. It branches off into various arteries that deliver blood to specific regions, ensuring proper circulation throughout the body. The descending aorta plays a critical role in maintaining the overall function and vitality of the body's systems by providing oxygen and nutrients to the lower parts of the body.
