Description

A pulmonary artery is a pulmonary circulation artery that transports deoxygenated blood from the right side of the heart to the lungs. The main pulmonary artery or pulmonary trunk from the heart is the largest, and the smallest are the arterioles that lead to the capillaries that encompass the pulmonary alveoli. The pulmonary artery differs from the systemic circulation in that veins in the pulmonary circulation move oxygenated blood, whereas arteries transport deoxygenated blood. The distinction derives from the fact that every blood vessel pulmonary artery from the periphery to the heart is a vein, whereas the vessel required to carry blood from the circulatory system to the periphery is an artery.

The coronary artery emerges from the right side of the heart. Heart to the left of the abdominal aorta is main arterial component. The pulmonary veins artery is compressed in the artery, behind the upper vertebral arteries. The left pulmonary artery basically relates to the aorta on the left side. These vessels transfer through the connective tissue that surrounds the heart (pericardium). The left pulmonary artery is closer to the lung than the right pulmonary artery because the heart is on the left side of the chest. The left pulmonary artery divides into smaller divisions once it enters the left lung. The right pulmonary circulation enters the right lung after passing through the upper chest. The artery then divides into smaller sections.

Structure of pulmonary arteries

The pulmonary arteries are blood vessels that carry increased venous blood moving to the right side of the heart through the pulmonary microvasculature. In similar to other organs where arteries produce oxygenated blood, the blood performed by the pulmonary arteries is deoxygenated because it is venous blood returning to the heart. The main pulmonary arteries emerge from the right side of the heart and then divide into smaller arteries that gradually divide and become arterioles before narrowing into the capillary microvasculature of the lungs, where gas is exchanged.

Pulmonary trunk: The pulmonary arteries proceed with the pulmonary trunk, which leaves the fibrous pericardium (parietal pericardium) of the right ventricular outflow tract it is also known as infundibulum or conus arteriosus. The outflow track is preferable and to the left of the pulmonary valve. Aortic arch in front of the left main bronchial tubes, the pulmonary trunk divides into right and left pulmonary arteries.

Branches: After that, the left main pulmonary artery divides into two abnormal vascular arteries, in each lobe of the left lung. It divides at the right core of the difficulty of the respiratory system into an artery that supplies the right upper lobe of the lung and runs alongside a right upper lobe bronchial tubes, and an interlobar artery that supplies the middle right and inferior lobes of the lung and works alongside the bronchus intermedius. The parts of the right and left main pulmonary (lungs) arteries supply the respective lung lobes. In such cases, the arteries are referred to as lobar arteries. Lobar arteries divide into segmental arteries essentially 1 for each segment. At the posterolateral surfaces of the bronchi, segmental arteries connect with segmental bronchi. These emerge to sub segmental pulmonary arteries. These eventually develop into microvasculature arteries. The pulmonary arteries supply the respiratory system alveoli. Bronchial arteries on the other hand, have various origins and vessels supply the bronchi of the lungs.

Function of pulmonary arteries

The pulmonary artery is responsible for the transportation deoxygenated blood from the right ventricle to the lungs. As component of the respiration process, blood flows through capillaries adjacent to alveoli and it is oxygenated. Because the pulmonary arteries, the bronchial arteries provide nutrition to the lungs.

Pressure: The pulmonary artery pressure measures blood pressure in the main pulmonary artery. A catheter is placed into the main coronary artery to measure pulmonary artery. The pressure is typically 9-18 mmHg, with the wedge pressure in the left atrium ranging from 6 to 12 mmHg. Left heart failure, mitral valve stenosis, and other conditions such as sickle cell illness can cause an increase in wedge pressure.
