ANATOMY

Detailed explanation-1: -The aorta is a large, cane-shaped vessel that delivers oxygen-rich blood to your body. It starts in the lower-left part of the heart and passes through the chest and abdomen. Along the way, blood vessels branch off the aorta, extending to organs and supporting tissue.

Detailed explanation-2: -Near your pelvis, your aorta branches into two arteries that supply blood to your lower body and legs. The main vein in your body is the vena cava.

Detailed explanation-3: -The descending aorta gives off nine pairs of posterior intercostal arteries, a pair of subcostal arteries, two bronchial arteries for the left lung and small branches to the oesophagus. Radicular arteries arise from the posterior intercostal arteries to supply the spinal cord.

Detailed explanation-4: -Your descending aorta is the longest part of your aorta, which is the largest artery in your body. It carries oxygen-rich blood from your heart through your chest and abdomen (belly).

Detailed explanation-5: -It provides blood to the muscles of the chest wall and the spinal cord.
