Question

The abdominal aorta divides into two branches before entering the legs. What are the names of these branches?

Answer 1

Hint: First of all we need to know what aorta and abdominal aorta are. So, the aorta is the main blood vessel of our body. It supplies blood all over our body. And the abdominal aorta is the main blood vessel that supplies blood in the abdominal cavity. It further bifurcates into two parts and enters each leg for oxygenated blood supply.

Complete Answer:
The abdominal aorta runs from the diaphragm and ends just above the pelvis. Here it divides into the iliac arteries. There are a total of five arteries that branch from the abdominal aorta. These are the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the renal arteries and the iliac arteries.
Abdominal aorta or Descending aorta is divided into two major branches. The right one is the Right common iliac artery and the left one is the Left common iliac artery. Both of these common iliac arteries are further divided into external iliac arteries and internal iliac arteries.

The right external iliac artery and the left external iliac artery enter respectively into the right and left leg and form the femoral arteries. These arteries enter into our legs in the thigh region. Femoral arteries are the main supplier of oxygenated blood in the lower extremity of our body.

Note:
The abdominal aorta is the largest artery of the human body and is the final section of the aorta. It is the continuation of the thoracic aorta. It starts at the twelfth thoracic vertebra and just near the diaphragm. And then it is divided into two parts at the first lumbar vertebrae.
