Ascending Branch Posterior Right Pulmonary Artery (Ramus Posterior Ascendens, Pna)

The ascending branch of the posterior right pulmonary artery (Ramus Posterior Ascendens, Pna): anatomical review

Arteries play an important role in the body as they are responsible for supplying blood and oxygen to tissues and organs. The Ramus Posterior Ascendence (Pna) is one of the branches of the right pulmonary artery and plays an important role in supplying blood to the posterior apical segment of the right lung.

Ramus Posterior Ascendence (Pna) arises from the right pulmonary artery and goes to the apical segment of the right lung. It runs along the posterior surface of the right lung and branches into several smaller arteries that supply blood to the apical segment.

It is important to note that the apical segment of the right lung has features in anatomy and function. It is located at the top of the right lung and has its own blood supply system. In addition, this segment plays an important role in breathing and is especially important for patients with lung diseases.

Ramus posterior ascension (Pna) may be involved in various pathologies such as pulmonary embolism, pulmonary ischemia or hemorrhage. In these cases, the affected segment of the lung may become insufficiently supplied with oxygen and blood, which can lead to various complications.

In conclusion, Ramus Posterior Ascendence (Pna) plays an important role in supplying blood to the posterior apical segment of the right lung. This highlights the importance of understanding the anatomy and function of the pulmonary arteries, which can help in the treatment of patients with lung disease and related complications.
