What are the branches of the abdominal aorta?

What are the branches of the abdominal aorta?

There are five arteries that branch from the abdominal aorta: the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the renal arteries and the iliac arteries.

What are the 3 branches of the aorta called?

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 3 major branches of the abdominal aorta?

The abdominal aorta has: Three single anterior visceral branches (coeliac, superior mesenteric artery, inferior mesenteric artery) Three paired lateral visceral branches (suprarenal, renal, gonadal)

What are the 5 branches of the aorta?

Here, we present a unique case with 5 branches of the aortic arch (AA), namely the right common carotid artery, left common carotid artery, left thyrocervical trunk, left subclavian artery and right subclavian artery (RSA), from right to left.

What are the first branches of the aorta?

The convexity of the aortic arch gives off three branches; the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. Brachiocephalic trunk: also called the brachiocephalic artery, is the first and largest artery that branches off the aortic arch.

What are the first two 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 are arterioles?

An arteriole is a small-diameter blood vessel which forms part of the microcirculation that extends from an artery and leads to capillaries. Capillary: Arterioles are part of the microcirculation system, along with capillaries, arteries, veins, venules, and tissue cells.

What are the three unpaired branches of abdominal aorta?

The branches of the abdominal aorta include three major unpaired trunks (celiac trunk, superior mesenteric, inferior mesenteric arteries), six paired branches, and an unpaired median sacral artery.

What is the largest branch of the abdominal aorta?

celiac trunk
The first and often largest visceral branch of the abdominal aorta is the celiac trunk. The celiac trunk quickly bifurcates or trifurcates into branches. The main branches are the common hepatic and splenic arteries, and, in the case of a trifurcation, the left gastric artery (see Figure 19).

What are the first five branches of the aorta?

What is the second branch of the aorta?

suprarenal artery
The suprarenal artery is the second branch from the abdominal aorta.

Where are the terminal branches of the aorta located?

The terminal branches of the abdominal aorta, the left and right common iliac arteries, arise from the bifurcation in front of the body of L4 vertebra about 1.25 cm to the left of the median plane. The common iliac arteries supply the lower limb, the gluteal region, and the pelvic viscera.

Is the ascending aorta the same as the descending aorta?

In addition, the ascending aorta, aortic arch and the thoracic part of the descending aorta are sometimes together referred to as the thoracic aorta, due to them all being confined to the thoracic cavity. This classification describes the aorta as having two parts; the thoracic and abdominal aorta.

Which is the last artery given off by the aortic arch?

Arising at the level of the sternal angle, the left subclavian artery is the last artery to be given off by the aortic arch, marking the termination of the aortic arch and the beginning of the descending aorta.

Which is the most common classification of the aorta?

There are a number of classifications of the aorta. Most common one, and the one we will use in this article, is the classification of the aorta into three parts; the ascending aorta, aortic arch and the descending aorta.
