Between these tentacle-like projections are tiny gaps called filtration slits that act like a sieve allowing only small particles such as water, glucose and ionic salts to pass through while blocking large proteins and red blood cells.

在这些触手状突出物之间有微小缝隙，称为滤孔；像筛一样只允许小物质如水、葡萄糖、盐等通过，而阻挡蛋白质、红细胞等。

So, when a germ gets inside and attacks your body, the immune system sees unusual foreign shapes on the surface, and then special cells in your body called white blood cells create antibodies that connect up.

所以，当细菌侵入并攻击你身体时，你免疫系统就会发现这些外观上不寻常异物，然后你身体中特殊细胞，即白细胞，会产生连接起来抗体。

Rather than editing the gene out, Dr. John Tisdale says his team added a copy of the normal correct gene which produced healthy blood cells.

约翰·蒂斯代尔博士说，他研究小组没有对病变基因进行编辑，而是添加了一份正常正确基因副本，该基因可以产生健康血细胞。
