The only branches of ascending aorta are the coronary arteries.

The three branches mentioned are not from ascending aorta but are from the arch of aorta which is a continuation of the ascending aorta.

The 3 branches are:

1. Brachicephalic trunk ( Innominate artery )

2. Left Common carotid

3. Left subclavian

This is a perennial trick question in Anatomy class. The first branches of the aorta (technically, the ascending aorta) are the right & left coronary arteries, which supply the heart.

Many anatomy students spend so much effort learning the asymmetry of the aortic arch branches, and will misread the question. Here, this question's phrase "aorta at its base" actually provides a clue; without that, it's more misleading.

The first branch to leave the aortic arch is the brachiocephalic artery (a/k/a innominate artery). This branch splits into two major arteries: the right subclavian artery (which soon splits into arteries that supply the right neck and thorax) and the right common carotid artery (which supplies the right side of head and neck).

The next artery to stem from the aortic arch is the left common carotid artery (which supplies the right side of head and neck, though it basically supplies different muscles) and the left subclavian artery.

A tortuous aorta refers to an anatomical variation where the aorta, the main artery of the body, has an abnormal, twisted shape. This can sometimes be a normal variant with no clinical significance, but in some cases it may be associated with other cardiovascular conditions or risk factors. Treatment is typically not necessary unless it is causing symptoms or complications.


Which chamber does the aorta comes from?

The aorta itself does not lead to a specific chamber of the heart. Upon the final stages of the contraction of the heart, blood that is present within the left ventricle of the heart is pumped out of the left ventricle, and is pushed into the aorta, which is the largest artery in the human body. The aorta itself gives rise to all of the other arteries of the body.


2 What does the aorta do?

Portion of the aorta in the abdomen?

There are actually more than one portion of the aorta that is in the abdominopelvic cavity. The left ventricle and thoracic aorta of the heart lead to the abdominal aorta which begins at the diaphragm. The abdominal aorta first branches into the inferior phrenic and celiac arteries, superior mesenteric and middle suprarenal arteries, renal and gonadal arteries, lumbar artery, inferior mesenteric artery, and the median sacral and common iliac arteries. From there, the artery splits to form the two common iliac arteries that carry blood to the legs.
