时差N小时 为什么脚底会磨出水泡?(下)

Blistering² occurs when an upper layer of skin rubs against the underlying³ layer.

当表皮与皮下层相互摩擦时，就会产生水泡。

As a space opens between the skin layers, chemicals cause the blood vessels⁴ in the area to leak and allow a clear fluid to seep⁵ out and fill the space between layers of skin.

当皮层之间形成隔离空间后，化学物质造成此区域血管渗透，从而有透明液体渗出，填充在皮层之间的部位。

This fluid is a sort of clear plasma⁶, or blood without the red blood cells.

这种液体是一种透明的血浆，或者可以说是没有红细胞的血液。

Blisters⁷ usually occur in the uppermost layers of skin, and are normally harmless.

水泡通常出现在皮肤表层，对人体无害。

Because the blood vessels are only made more porous⁸ but not actually damaged, red blood cells do not fill the blister¹.

血管只是多了一些空隙，实际并未遭到破坏，红细胞也不会出现在水泡内。

But if a blister does fill with red blood, it means the damage is more serious, and should be carefully treated.

如果水泡内出现红色液体，这就意味着血管损伤比较严重，需谨慎处理。
