What is the anatomical location of the aorta?

What is the anatomical location of the aorta?

The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch. It then continues downward into the abdomen, where it branches into the iliac arteries just above the pelvis.

Where is the thoracic aorta?

Thoracic aorta: The thoracic aorta is a section of the aorta, the largest artery in the body, within the chest. Specifically, the thoracic aorta is that part of the aorta that starts after the arch of the aorta and runs down to the diaphragm, the great muscle that separates the chest from the abdomen.

What artery is a branch of the thoracic aorta?

The major noncoronary branches of the thoracic aorta are (in order) the innominate (also known as the brachiocephalic) artery, the left common carotid artery, and the left subclavian artery. The innominate artery bifurcates into the right common carotid and right subclavian arteries.

What are 3 branches of the thoracic aorta?

The arch of the aorta has three branches: the brachiocephalic artery (which divides into right common carotid artery and the right subclavian artery), the left common carotid artery, and the left subclavian artery. These arteries provide blood to both arms and the head.

What are the branches of the aorta called?

The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries.

What is the first part of the aorta called?

The aorta is divided into three parts: the ascending aorta (where the aorta initially leaves the heart and points toward the head), the arch of the aorta (where the aorta changes direction), and the descending aorta (where the aorta points toward the feet).

Does the aorta run along the spine?

At its commencement, it is situated on the left of the vertebral column; it approaches the median line as it descends; and, at its termination, lies directly in front of the column. The descending thoracic aorta has a curved shape that faces forward, and has small branches….Descending thoracic aorta.

The arch of the aorta has three branches: the brachiocephalic artery (which divides into right common carotid artery and the right subclavian artery), the left common carotid artery, and the left subclavian artery.

What is the main function of the aorta?

The aorta is the main artery that carries blood away from your heart to the rest of your body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.

Where does the aorta receive blood from?

Aorta Anatomy The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.

What are the first branches of the aorta?

The first branch of the aorta is normally the innominate artery, which is also referred to as the brachiocephalic trunk. Shortly after its origin, the innominate artery divides into the right subclavian and right common carotid arteries.

What’s the difference between an artery and an aorta?

Difference Between Aorta and Artery. August 17, 2018 Posted by Samanthi. The key difference between aorta and artery is that the aorta is the biggest artery that carries oxygenated blood from the heart, while artery is a blood vessel that carries oxygenated blood into other organs, tissues, and cells in our body.

Where is the femoral artery located in the human body?

Femoral pulse As the femoral artery is relatively superficial within the femoral triangle, the femoral pulse is usually easily palpated. It can be palpated midway between the anterior superior iliac spine and pubic symphysis, just inferior to the inguinal ligament.

Is the aorta on the left or the right?

The aorta, normally on the left side of the body, may be found on the right in dextrocardia, in which the heart is found on the right, or situs inversus, in which the location of all organs are flipped. Variations in the branching of individual arteries may also occur.

Where does the ascending aorta supply blood to?

Ascending branches of aorta provide blood to the heart while aortic arch gives blood to head, neck and arm region. The branches arising from the thoracic descending aorta supply oxygenated blood to the chest while branches from the abdominal aorta supply the abdomen. Common iliac arteries supply blood to legs and pelvis.

The key difference between aorta and artery is that the aorta is the biggest artery that carries oxygenated blood from the heart, while artery is a blood vessel that carries oxygenated blood into other organs, tissues, and cells in our body.

Is the aortic arch part of the ascending aorta?

The aortic arch is the part of the aorta between the ascending aorta and thoracic descending aorta. The sharpness of the angle can be different among individuals. The aortic arch gives rise to three arterial branches: Brachiocephalic artery, which supplies blood flow to the right arm and right carotid artery to the right side of the brain.

Femoral pulse As the femoral artery is relatively superficial within the femoral triangle, the femoral pulse is usually easily palpated. It can be palpated midway between the anterior superior iliac spine and pubic symphysis, just inferior to the inguinal ligament.

What causes variations in the aorta and its branches?

Variations in the abdominal aorta and its branches are very common and usually occur as a result of changes that occur during embryologic development. The arteries that show frequent variations include the celiac trunk, superior mesenteric artery, the renal artery, and the testicular arteries.
