Phagocytosis
吞噬作用
Phagocytosis is the name given to the process by which a cell wraps part of its cell membrane around an external particle and envelopes it, taking it into the cell (endocytosis).
吞噬作用是指细胞将细胞膜的一部分围绕外部粒子包裹并将其包围，将该粒子摄入细胞（内吞作用）的过程。
The scenario depicted here is that of phagocytosis of some material, then the formation of a vescicle to hold the material, then the merging with a lysosome which breaks down the material. The vesicle movements required are aided by microfilaments from the cytoskeleton.
此处所示的场景是吞噬某些物质，随后形成一个囊泡以容纳这些物质，然后与溶酶体融合，溶酶体将分解这些物质。囊泡的运动由细胞骨架中的微丝所协助。
Phagocytosis is a common way for a cell to take in food particles. It is also used by leukocytes (white blood cells) to surround invading bacteria, viruses and other foreign material. These kinds of cells are sometimes called phagocytes because of this function.
吞噬作用是细胞摄取食物颗粒的一种常见方式。它也被白细胞用来包围入侵的细菌、病毒和其他外来物质。这类细胞因此有时被称为吞噬细胞。
