Artery Pulmonary Left

The left pulmonary artery (a.pulmonalsinistra, PNA) is a paired vessel that carries oxygenated blood from the left atrium to the lungs. It is one of the two main pulmonary arteries that form the largest human circulatory system, the pulmonary artery. Thanks to this artery and other vessels of the pulmonary circulation, blood is pumped from the heart to the lungs and returns back through the capillaries to be oxygenated.

The left pulmonary artery is a complex structure that has two branches, each of which continues into the right ventricle. There are also additional arteries running from the left common iliac artery to the left pulmonary artery. This arterial system performs a vital function as it constantly transports five liters of blood per minute to the lungs. In turn, the lungs use oxygen extracted from the air to enrich the blood, which is then transported to the aortic arch.

The structure and shape of the left pulmonary artery may vary depending on the individual. In some people this artery may be larger in size, in others it may be much smaller. Larger left lung arteries may be associated with decreased lung function and an increased risk of cardiovascular disease such as congestive heart failure.

Overall, the pulmonary artery on the left plays a key role in regulating blood circulation in the lungs, the functioning of the heart and maintaining the health of the entire body. It is necessary to understand that if this artery does not function sufficiently, there may be a delay in blood supply to the lungs, as well as a decrease in circulating blood volume and increased pressure in the circulatory system. Thus, it is important to maintain a healthy lifestyle and eat right to prevent left pulmonary artery problems from occurring.
