Of the visceral branches, the celiac artery and the superior and inferior mesenteric arteries are unpaired, while the suprarenals, renals, internal spermatics, and ovarian are paired. Of the parietal branches the inferior phrenics and lumbars are paired; the middle sacral is unpaired.
What are the unpaired visceral branches?
The unpaired visceral arteries supply the gastrointestinal (GI) tract, spleen, pancreas, gallbladder, and liver and are made up of the celiac trunk, superior mesenteric artery (SMA), and inferior mesenteric artery (IMA).
Which of the following branches of the abdominal aorta are paired?
The branches of the abdominal aorta: Paired branches: the middle adrenal, renal, gonadal, inferior phrenic, and lumbar arteries. Unpaired branches: the coeliac, superior mesenteric, inferior mesenteric, and median sacral arteries.

What are the 3 major branches of the abdominal aorta?
The abdominal aorta has: 3 single anterior visceral branches (coeliac, superior mesenteric artery, inferior mesenteric artery) 3 paired lateral visceral branches (suprarenal, renal, gonadal) 5 paired lateral abdominal wall branches (inferior phrenic and four lumbar)
Where is the abdominal aorta located in the body?
The abdominal aorta runs from the diaphragm and ends just above the pelvis, where it divides into the iliac arteries. 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.
Which are the 3 major unpaired branches of the 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 function of the abdominal aorta?
It is a continuation of the thoracic aorta. It begins at the diaphragm, and runs down to the point where it ends (by splitting in two to form the common iliac arteries). The abdominal aorta supplies oxygenated blood to all of the abdominal and pelvic organs and the legs.
What is the first branch of the abdominal aorta?
The first and often largest visceral branch of the abdominal aorta is the celiac trunk. The celiac trunk quickly bifurcates or trifurcates into branches.
At what level does the abdominal aorta bifurcate?
The abdominal aorta bifurcates at the L4 level. The small median or middle sacral artery arises from the posterior surface of the abdominal aorta close to the bifurcation and descends vertically along the pelvic surface of the sacrum.
What is the first branch of the abdominal aorta quizlet?

Which of these is the major tributary of the superior vena cava quizlet?
The azygos vein is the major tributary of the superior vena cava (SVC).
Which vessels supply blood to the head the upper limb the abdominal wall the lower limb?
The superior vena cava is formed by the left and right brachiocephalic veins, which receive blood from the upper limbs, head and neck. The inferior vena cava returns blood from the abdomen and lower limbs.
Why do I feel a pulse in my stomach?
You’re most likely just feeling your pulse in your abdominal aorta. Your aorta is the main artery that carries blood from your heart to the rest of your body. It runs from your heart, down the center of your chest, and into your abdomen. It’s normal to feel blood pumping through this large artery from time to time.
What organs does the abdominal aorta supply?
In the abdominal cavity the aorta gives off a number of branches, which form an extensive network supplying blood to the stomach, liver, pancreas, spleen, small and large intestines, kidneys, reproductive glands, and other organs.
How many branches does the aorta have?
