The aorta is the primary and the largest artery of the human body that transports blood away from the heart to the rest of the body. After the blood is carried out from the heart through the aortic valve, it travels across the aorta, making a cane-shaped curve that connects with other major arteries to deliver oxygenated blood to the brain, muscles, and other cells. By doing this, the aorta takes part in the systemic blood circulation in the body.The ascending aorta supplies blood to the heart.The aortic heart supplies blood to the left side of the brain and neck and the left armThe descending aorta supplies blood to the oesophagus, pericardium, diaphragm, lump nodes, ribs and some structures of the heart.The abdominal aorta carries blood to several parts of the body which includes  The liver  Diaphragm,  Stomach  Spleen  Abdominal oesophagus  Intestines  Kidneys  Spinal cord  Pancreas.
