Drag the labels onto the diagram to identify respiratory system structures. One of 80 million bronchioles Alveolar air space Muscles of expiration Alveolus Branch of pulmonary vein Alveoli - Branching of airways Structure of lung lobule Muscles of inhalation Alveolar epithelium Nucleus of endothelial cell Exchange surface of alveoli Plasma RBC Branch of pulmonary artery 0.1-1.5 um Capillary Surfactant Fused Larynx membranes Blue arrow represents gas exchange
The system is divided in the upper and lower respiratory tracts. Label the diagram below using the following list of upper and lower respiratory structures: alveoli, trachea, nose, bronchioles, pharynx, bronchi, larynx, epiglottis.
