alveolar ducts造句

• There are five or six alveolar sacs associated with each alveolar duct.
• In human anatomy, respiratory bronchioles exist proximal to the alveolar ducts.
• Later divisions including the respiratory bronchiole, alveolar ducts and alveoli, are specialized for gas exchange.
• These in turn supply air through alveolar ducts into the alveoli, where the exchange of gases take place.
• The alveolar ducts and alveoli consist primarily of simple squamous epithelium, which permits rapid diffusion of oxygen and carbon dioxide.
• These consist of a respiratory bronchiole, which branches into alveolar ducts and alveolar sacs, which in turn divide into alveoli.
• Exchange of gases between the air in the lungs and the blood in the capillaries occurs across the walls of the alveolar ducts and alveoli.
• Histologically, cryptogenic organizing pneumonia is characterized by the presence of polypoid plugs of loose organizing connective tissue ( Masson bodies ) within alveolar ducts, alveoli, and bronchioles.
• The alveoli are located in the respiratory zone of the lungs, at the ends of the alveolar ducts and alveolar sac, representing the smallest units in the respiratory tract.
• Another type of cell, known as an alveolar macrophage, resides on the internal surfaces of the air cavities of the alveoli, the alveolar ducts, and the bronchioles.
• Lung alveoli are the ends of the respiratory tree, branching from either alveolar sacs or alveolar ducts, which like alveoli are both sites of gas exchange with the blood as well.
• The tertiary bronchi divide into many smaller bronchioles which divide into terminal bronchioles, each of which then gives rise to several respiratory bronchioles, which go on to divide into two to eleven alveolar ducts.
• |Alveolar duct " tiny ducts that connect the respiratory bronchioles to alveolar sacs, each of which contains a collection of alveoli ( small mucus-lined pouches made of flattened epithelial cells ) ."
• If nitrogen dioxide poisoning is untreated, fibrous granulation tissue is likely to develop within the alveolar duct, a tiny ducts that connect the respiratory bronchioles to alveolar sacs, each of which contains a collection of alveoli ( small mucus-lined pouches made of flattened epithelial cells ).
