Pneumocytes are the primary cell type found in the alveolar lining of the lungs.
翻译：肺泡上皮中的主要细胞类型就是肺泡细胞。
Type I pneumocytes constitute about 95% of the alveolar epithelial cells and are responsible for gas exchange.
翻译：Ⅰ型肺泡细胞构成了大约95％的肺泡上皮细胞，负责气体交换功能。
Type II pneumocytes produce and secrete pulmonary surfactant to reduce surface tension within the alveoli.
翻译：Ⅱ型肺泡细胞产生并分泌肺表面活性物质，以降低肺泡内的表面张力。
Pneumocytes can be damaged by exposure to harmful particles or chemicals, leading to inflammation and potential respiratory diseases.
翻译：肺泡细胞在接触到有害颗粒或化学物质时可能会受损，导致炎症和潜在的呼吸道疾病。
The regeneration of pneumocytes is critical following lung injury as they play a key role in maintaining lung function.
翻译：由于肺泡细胞在维持肺部功能中起着关键作用，因此在肺损伤后其再生至关重要。
In COVID-19 patients, severe infection can lead to diffuse alveolar damage involving both types of pneumocytes.
翻译：在COVID-19患者中，严重的感染可能导致涉及两种类型的肺泡细胞弥漫性肺泡损伤。
Pneumocytes exhibit remarkable plasticity under certain conditions, allowing them to differentiate into other cell types for repair purposes.
翻译：在特定条件下，肺泡细胞表现出显著的可塑性，能够分化为其他类型的细胞以进行修复。
Electron microscopy revealed that the virus had invaded and replicated within the cytoplasm of the pneumocytes.
翻译：电子显微镜观察显示，病毒已经侵入并在肺泡细胞的细胞质内复制。
Pneumocytes have an essential role in clearing away inhaled particles and microorganisms from the alveolar space.
翻译：肺泡细胞在清除吸入的粒子和微生物从肺泡空间中有至关重要的作用。
Smoking can cause oxidative stress in pneumocytes, increasing their susceptibility to various lung diseases.
翻译：吸烟会导致肺泡细胞遭受氧化应激，增加它们对各种肺部疾病的易感性。
