Which are the first arteries to branch off the aorta?

Answer 1

The aorta is usually divided into five segments/sections:

1. Ascending aorta: the section between the heart and the arch of aorta

2. Arch of aorta-the peak part that looks somewhat like an inverted "U"

3. Descending aorta-the section from the arch of aorta to the point where it divides into the common iliac arteries

4. Thoracic aorta-the half of the descending aorta above the diaphragm

5. Abdominal aorta-the half of the descending aorta below the diaphragm

Answer 3

• The celiac trunk- supplies blood to the stomach, part of the duodenum, part of the pancreas, the liver and the spleen
• The superior mesenteric artery- supplies most of the small intestines, the pancreas, and the proximal portion of the large intestines
• The inferior mesenteric artery- supplies the distal part of the transverse colon, the descending colon, the sigmoid colon and the rectum

Answer 4

branches of abdominal aorta are classified into three.

these are : ventral branches, dorsal branches and lateral branches.

ventral branch consists of : coeliac artery (at T12 vertebral level ).

superior mesenteric artery(at L1 level).

inferior mesenteric artery(at L3 level).

dorsal branch consists of : right and left lumbar arteries.

median sacral artery.

lateral branches consists : right and left inferior phrenic arteries.

right and left suprarenal arteries.

right and left renal arteries.

right and left gonadal arterries.

terminal branches are right and left common illiac arteries.

Answer 5

The right and left coronary arteries branch off of the base of the ascending aorta.

Answer 6

Coronary arteries
