Lateral Branch of the Pulmonary Artery

The lateral branch (ramus) of the pulmonary artery (arteriae pulmonalis) is a branch from the main trunk of the pulmonary artery, which is located on its lateral surface and provides blood supply to the lungs. It is one of the main vessels that circulate blood in the lungs and plays an important role in maintaining the health of the respiratory system.

The lateral branch has several functions. First, it distributes blood more efficiently between the lungs, which helps keep them functioning properly and prevent congestion. The lateral branch is also involved in regulating pressure in the pulmonary vessels and maintaining normal oxygen levels in the blood.

In addition, the lateral artery can be damaged by certain diseases, such as thrombosis or pulmonary embolism. This can impair blood flow in the lungs and cause serious complications such as hypoxia and heart failure.

To prevent damage to the lateral branch of the pulmonary artery and maintain lung health, regular medical examinations, including ultrasound and ECG, are recommended. It is also important to maintain a healthy lifestyle, including proper nutrition, physical activity and avoidance of smoking and alcohol.

The lateral branch, also known as the superior circumflex artery, is a branch of the pulmonary artery that passes around the upper part of the left half of the lungs through the diaphragm and branches into the lower lobe of the left lung under the right dome of the diaphragm.

The lateral branch arises from the pulmonary artery below and to the left of the thoracic branch (branchio-lobar artery), near the anterior branch and branches of the middle lobe of the left pulmonary artery. Going in a transverse direction, it passes through the spleen and into the head of the pancreas in the right diaphragm. The lateral basin then lies on the right lung below the diaphragm around the choroid-bronchial ligament. AND
