5 天之前 · Thoracic Aorta. The thoracic (descending) aorta spans from the level of T4 to T12. Continuing from the aortic arch, it initially begins to the left of the vertebral column but approaches the midline as it descends. It leaves the thorax via the aortic hiatus in the diaphragm, and becomes the abdominal aorta. Branches. In descending order:

The descending thoracic aorta begins at the lower border of the fourth thoracic vertebra and ends in front of the lower border of the twelfth thoracic vertebra, at the aortic hiatus in the diaphragm where it becomes the abdominal aorta.

2021年3月16日 · It can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta, and the abdominal aorta (Fig. 8‑1). The aorta ascends obliquely to the right within the pericardium, between the superior vena cava and main pulmonary artery, and anterior to the right pulmonary artery and trachea (ascending aorta).

2023年10月30日 · The branches of the thoracic aorta can be divided into visceral branches, intended largely for the organs of the mediastinum, and parietal branches, intended for the structures of the thoracic wall. The visceral branches are the pericardial, bronchial, esophageal and mediastinal branches, while the parietal branches are intercostal, subcostal ...

Descending aorta: Long, straight segment that runs from your chest (thoracic aorta) to your abdominal area (abdominal aorta). What are the aorta’s branches? Many smaller blood vessels branch off from the aorta, including: Ascending aortic branches. Coronary arteries supply blood to muscle tissue in your heart. Aortic arch branches

The descending thoracic aorta continues branching into eleven pairs (right and left) of posterior intercostal arteries. A pair of superior phrenic arteries (right and left) branch from the aorta to serve the superior diaphragm.

2019年8月7日 · The thoracic aorta extends from the aortic annulus to the diaphragm. The thoracic aorta can be divided into three major parts: the ascending aorta, the aortic arch, and the descending thoracic aorta ( Fig. 44-5 ). The aortic root and the tubular ascending aorta comprise the ascending aorta.

Branches from the thoracic aorta include the bronchial arteries, the mediastinal arteries, the esophageal arteries, the pericardial arteries, and the superior phrenic artery. The thoracic aorta and the esophagus run parallel for most of its length, with the esophagus lying on the right side of …

Branches: Third to eleventh posterior intercostal, subcostal, esophageal, bronchial, superior phrenic, mediastinal, and pericardial arteries. Supplied Structures: Thoracic viscera, thoracic wall, and respiratory diaphragm.

The thoracic aorta has two groups of branches: The parietal branches, which supply the walls of the thoracic cavity, the diaphragm, and most of the anterior abdominal wall with blood. The visceral branches, which supply the thoracic organs with blood. The parietal branches include:
