What is a descending aorta?

Aorta is the largest artery in the body and has the primary purpose of carrying blood from the heart to other parts of the body. It is somewhat shaped like candy. The short side of Candy Cane is called ascending aorta. The long side of the "sugar cane" is known as descending aorta. The curved part of the "sugar cane" - a part that connects the long side (descending aorta) and the short side (ascending aorta) together - is called the aortic arch. The descending aorta itself is divided into two parts based on their location in the body - thoracic aorta and abdominal aorta. It continues down to T12 and ends in the membrane. There are seven arterial branches from the thoracic aorta. Of these seven, they belong to the group of visceral branches and three are parietal branches.

Visceral branches include pericardial, bronchial, esophageal and mediastinal arterial branches. Visceral branches give oxygenated blood to the outer walls of the heart, lungs, esophagus thying glands and lymph nodes. This blood will deliver to inter -ling -up muscles between ribs, abdominal muscles and membraneu.

Aorta abdominal descending aorta continues where the thoracic aorta leaves. It starts at the vertebra T12 thoracic spine and ends on L4 - fourth vertebra in the lumbar spine. The end of the abdominal aorta is also the end of the whole aorta. From there, the aorta branches into two arteries - the left normal iliac arteries and the right common iliac artery. They travel down each of their feet to give blood to the lower limbs.

While the thoracic aorta has seven branches, Abdominal aorta has 11. 11 branches of abdominal aorta can be divided into three groups - visceral, parietal and terminal branches. These branches give oxygenated blood to the organs in the abdomen, pelvis and both legs.

Visceral branches are celiaciac, superior mesenteric, lower mesenteric, medium suprarenals and renals. In addition, men also have an inner sperm branch, while women have a corresponding ovarian branch. Celiaciac, superior mesenteric and subordinate mesenteric artery and itThe branches give oxygenated blood to the stomach, liver, gall bladder, spleen, pancreas, intestines and addition. Medium suprarenal and renal arteries supply blood to the kidneys and secretion organs. Sperm arteries and ovarian arteries supply oxygenated blood to the corresponding reproductive organs, namely the testes and vas deferens in men and ovaries in women.

Parietal branches are lower frenics, the lumbar medium sacral. From the parietal branches, the lower frenic arteries supply blood to the membrane. The lumbar arteries supply blood most abdominal muscles. Medium sacral branches supply blood to the Sacrum and Coccyx and rectum. It also associates with an iliakal vein.

Finally, terminal branches are called common Iliacs. The common branches of the iliac arteries are decorated with the formation of outer and internal iliakal arteries that give the legs oxygenated with blood.
