31. A lung biopsy would show thickened alveolar septa with fluffy eosinophilic exudate in the alveoli . 32. Oxytocin stimulates contraction of the myoepithelial cells surrounding the alveoli , which already hold milk. 33. The "'alveolar septum "'separates adjacent alveoli in lung tissue. 34. The traditional truss spaces become alveoli of varied forms whose appearance invites very different perspectives. 35. The presence of alveoli and other traits place the Apicomplexa among a group called the alveolates. 36. Type II are larger and they line the alveoli and produce and secrete ELF and surfactant. 37. Alveoli are particular to mammalian lungs.38. Pulmonary surfactants are also naturally secreted by type II cells of the lung alveoli in mammals. 39. In a secondary phase, endothelial dysfunction causes cells and inflammatory exudate to enter the alveoli . 40. Surfactants reduce surface tension more readily when the alveoli is smaller because surfactants are more concentrated.
