Each one enters the respective lung at a structure known as the <strong>hilum<\/strong>.<\/li>\n\n\n\n<li><strong>Secondary Bronchi (Lobar Bronchi)<\/strong>: The primary bronchi further divide into secondary bronchi. The right lung, having three lobes, gets three secondary bronchi, while the left lung, with two lobes, receives two secondary bronchi.<\/li>\n\n\n\n<li><strong>Tertiary Bronchi (Segmental Bronchi)<\/strong>: Each secondary bronchus divides further into smaller tertiary bronchi. These bronchi supply air to specific segments of the lung.<\/li>\n\n\n\n<li><strong>Bronchioles<\/strong>: Tertiary bronchi continue branching into even smaller tubes called <strong>bronchioles<\/strong>, which eventually lead to the alveoli, the small air sacs where oxygen is exchanged with carbon dioxide in the blood.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Function:<\/h3>\n\n\n\n<p>Oxygen is carried by inhaled air through these branching bronchi and bronchioles until it reaches the alveoli, where gas exchange takes place. While each lung starts with one primary bronchus, the multiple branching bronchi and bronchioles ensure that oxygen is distributed efficiently throughout the lung&#8217;s entire surface area. This vast network ensures that the oxygen needs of the body are met effectively.<\/p>\n\n\n\n<p>Thus, the idea that each lung is fed by just one bronchus is an oversimplification, as the lungs are fed by an extensive, branching system of airways.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Each lung is fed oxygen by a separate bronchus. true or false?
