The Aorta The Aorta
The Aorta is the largest artery of the body, which carries the oxygenated blood from the left ventricle and supplies it to all the parts of the body. The Aorta initially is one inch wide in diameter. The aorta is classified as a large elastic artery. The Aorta
Division of the Division of the Aorta by Aorta by anatomical anatomical compartment compartment The Aorta is divided into two compartments The Thoracic aorta or thoracic portion of the aorta runs from the heart to the diaphragm. The Abdominal aorta or abdominal portion of the aorta from the diaphragm to the aortic bifurcation
Division of the Division of the Aorta by Aorta by course and course and direction of direction of blood flow blood flow The ascending Aorta, which travels superiorly from the heart and then makes a hairpin turn known as the aortic arch. Following the aortic arch, the aorta then travels inferiorly as the descending aorta and ends by dividing into two major blood vessels, which are the common iliac arteries and a smaller midline vessel, the median sacral artery
The first branch of the abdominal aorta is the Celiac trunk/ Axis Branches of Branches of abdominal abdominal Aorta Aorta It branches off into splenic artery and common hepatic artery The splenic artery is the largest branch of the celiac trunk, it feeds the spleen, the body and tail of the pancreas The common hepatic artery branches into the gastroduodenal artery and proper hepatic artery. The second main branch of the abdominal aorta is the Superior Mesenteric Artery (SMA). It is located posterior to the splenic vein and pancreas, the left renal vein is posterior to SMA and anterior to aorta. The third branch of the abdominal aorta is the right and left real arteries, the RRA is longer than the LRA The fourth branch of the abdominal aorta is the Inferior Mesenteric Artery
The aorta supplies all of the systemic circulation, except for the respiratory zone of the lung. Branches from the ascending aorta supply the heart. Branches from the aortic arch supply the head, neck and arms. The pelvis and legs get their blood from the common iliac arteries. Function of Function of the the Aorta Aorta
