Each bronchus divides into secondary bronchi, then into tertiary bronchi, which in turn divide, creating smaller and smaller diameter bronchioles as they split and spread through the lung. Air enters the lungs through the two primary (main) bronchi (singular: bronchus). Why do receptors in the bronchioles promote reflexive constriction while the stretch receptors in the larger airways mediate cough and sneeze reflexes Coughing and sneezing help to prevent any allergens or any other pathogens or particles from getting into the lungs. In the lungs, air is diverted into smaller and smaller passages, or bronchi. To accommodate the heart, the left lung is smaller and has only two lobes. The right lung is made of three lobes and is larger. Study with Quizlet and memorize flashcards containing terms like The process of supplying the body with O2 and removing CO2 is known as, 3 basic steps of respiration are:, Pulmonary ventilation is and more. This content does not have an Arabic version. This is therefore termed anatomical dead space as it serves no respiratory function. Anatomical dead space is increased because all these agents are bronchodilators. All inhalational agents increase both anatomical and alveolar dead space. Endotracheal tubes, tracheostomy decreases the anatomical dead space by bypassing the upper airways. This content does not have an English version. All anesthesia circuits, masks, humidifiers increase the anatomical dead space. It's one of the conditions that make up chronic obstructive pulmonary disease (COPD). \): The trachea bifurcates into the right and left bronchi in the lungs. Emphysema is a lung problem that makes it hard to catch your breath.
