The descending aorta travels down and goes across diaphragm to enter abdomen
(Abdominal Aorta).
Abdominal aorta supplies the intestine and all the organs in the abdomen.
The branches of Abdominal aorta are
● Coeliac Artery – supplies liver, spleen, gallbladder and pancreas
● Superior Mesenteric Artery – Supplies the intestines
● Inferior Mesenteric Artery – Supplies the intestines
● Renal Arteries – Normally one for either side and supplies kidney
Aorta has very specific branches at specific locations that supply specific parts of
the body.
Any disease that affect the aorta in a particular location will affect the
corresponding organs.The symptoms of the same disease at different locations can
thus be different.
After giving off these branches aorta divides into two large branches called
Common Iliac Arteries(CIA) one for either side. CIA's in turn divide into Internal
and External Iliac Arteries. Internal Iliacs supply the pelvic organs. External Iliacs
go on to become the femoral arteries that supply legs.
