One of its main components is the <strong>trachea<\/strong>, a rigid tube supported by cartilage rings, which ensures an open airway. It bifurcates into the <strong>left and right main bronchi<\/strong>, each entering its respective lung.<\/p>\n\n\n\n<p>Once inside the lungs, the main bronchi divide into <strong>lobar bronchi<\/strong>, also known as secondary bronchi, which supply the lobes of the lungs\u2014three in the right lung and two in the left. The <strong>segmental bronchi<\/strong>, or tertiary bronchi, further subdivide within each lobe and direct air to smaller regions called bronchopulmonary segments.<\/p>\n\n\n\n<p>The <strong>lungs<\/strong> are the principal organs where gas exchange occurs. The <strong>right lung<\/strong> has three lobes, making it larger than the left. Each lung is encased in a protective serous membrane called the <strong>pleura<\/strong>, and the <strong>pleural cavity<\/strong> between its layers is filled with fluid to reduce friction during respiration.<\/p>\n\n\n\n<p>At the base of the lungs lies the <strong>diaphragm<\/strong>, a key respiratory muscle. Its contraction during inhalation expands the chest cavity and reduces intrathoracic pressure, drawing air into the lungs. During exhalation, the diaphragm relaxes and returns to its dome shape, pushing air out.<\/p>\n\n\n\n<p>Each part of the respiratory system works in harmony to facilitate efficient air flow, protect the body from pathogens, and maintain acid-base balance through gas exchange.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Correctly label the components of the respiratory system.
