A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.
Heart failure; Bone fracture; Hiatal hernia; Pulmonary tuberculosis; Chest radiographs are used to diagnose many conditions involving the chest wall, including its bones, and also structures contained within the thoracic cavity including the lungs, heart, and great vessels.

structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein; structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs [1]
A typical pair of human lungs contains about 480 million alveoli, [11] providing a total surface area for gas exchange of between 70 and 80 square metres. [10] Each alveolus is wrapped in a fine mesh of capillaries covering about 70% of its area. [12] The diameter of an alveolus is between 200 and 500 μm. [12]
Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
The root of the right lung lies behind the superior vena cava and part of the right atrium, and below the azygos vein.That of the left lung passes beneath the aortic arch and in front of the descending aorta; the phrenic nerve, pericardiacophrenic artery and vein, and the anterior pulmonary plexus, lie in front of each, and the vagus nerve and posterior pulmonary plexus lie behind.
Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
Diagram of bronchoscopy . It is crucial to determine if a patient has an acute upper airway obstruction. Respiratory distress can rapidly lead to respiratory failure without appropriate management. [2] Thus, the first step is to conduct an urgent and comprehensive assessment of ABCs (airway, breathing, and circulation). [1]
