Sometimes this meant blending mechanical and replacement techniques, like on Spazzatura.

有时这意味着混合机械和替换技术，例如 Spazzatura。

For example, we have mechanical techniques like coughing, a mucociliary escalator that lines the entire airway and moves out larger bacteria, and macrophages that are nestled deep inside the alveoli and ready to destroy anything that lands there.

例如，我们有像咳嗽这样的技能，贴在气道的黏膜纤毛可移除较大的细菌，而巨噬细胞则在肺泡深处准备吞噬降解那里的东西。
