Alveolar macrophages then eat up these red blood cells, which causes them to take on this brownish color from iron build-up.

肺泡巨噬细胞之后会吞噬这些红细胞，导致这些细胞由于铁元素积聚而呈现棕褐色。

It has the ability to stop phagolysosomal fusion, and survive and replicate inside alveolar macrophages.

它可以阻止吞噬体和溶酶体融合，从而在肺泡巨噬细胞内生存并增殖。

Bacterial growth and death of alveolar macrophages produce powerful chemotactic factors that cause a large influx of polymorphonuclear leukocytes and monocytes from the peripheral blood.

军团菌的增长及肺泡巨噬细胞的死亡产生了强大的趋化因子，造成大量多形核白细胞和单核细胞从外周血涌入。

Once it reaches the lungs, it gets ingested by alveolar macrophages and inside macrophages, it gets wrapped up in a vesicle called phagosome, which normally merges with lysosomes to kill invading bacteria.

进入肺内后，它就会被肺泡巨噬细胞吞噬；在巨噬细胞内，它被包裹在称为吞噬体的囊泡中，通常吞噬体会与溶酶体融合，清除入侵的细菌。

Within days, the measles virus spreads through local tissue and is picked up by dendritic cells and alveolar macrophages, and carried from that local tissue in the lungs to the local lymph nodes.

几天之内，麻疹病毒通过局部组织传播，被树突状细胞和肺泡巨噬细胞捕获，并从肺部的局部组织被带到局部淋巴结。
