Arteries Diaphragmatic Thoracic

The phrenic thoracic arteries (a. phrenicae thoracae) are branches from the thoracic aorta (a. aortae thoracis). They supply blood to the diaphragm and adjacent organs.

The phrenic thoracic arteries emerge from the thoracic aorta at the level of the fifth and sixth costal cartilages. They head down to the diaphragm, where they divide into two branches: the right and left phrenic artery. Each phrenic artery runs along the corresponding side of the diaphragm, supplying blood to its muscle tissue, as well as adjacent organs - the liver, spleen and kidneys.

Venous drainage from the diaphragm occurs through the phrenic veins, which drain into the inferior vena cava.

The phrenic (or thoracic) arteries are two vessels that supply blood to the chest tissue and diaphragm. They are branches of the descending aorta, which is located in the chest area. The phrenic arteries are formed by paired right and left thoracic arteries. They are found in the posterior mediastinum or thoracic region of each rib. Their function is to supply blood to the diaphragm, sternum, ribs, and teeth of the upper jaw. They also provide nutrition to the muscles of the chest wall. An important feature of the arteries is their interaction with the intercostal and phrenic nerves. If these arteries are damaged, numbness of the chest tissue and pain in this area may occur.
