Right Pulmonary Artery

Last updated: May 5th, 2025

The right pulmonary artery is also known as the right branch of the pulmonary artery. It is a thicker artery, and a longer one, compared to the left pulmonary artery. The right pulmonary artery provides the right lung's blood supply; it runs down to the root of the right lung and from there it branches out into two separate arteries. These smaller arteries each transport blood to one of the lung's right lobes.
