To counteract this oxygen would have to be diluted with non reactive gas.

为了制造这种情况，氧中的空比率需要利用惰性体来降低。

But it gets even better, as the oxygen of the air bubble runs out, new oxygen diffuses into the bubble from the water around, it while the carbon dioxide diffuses outwards into the water.

但不只如此，外膜中的氧用完时，新的氧从周围的水扩散到膜内，而二氧化碳向外扩散到水中。

但是只有这一点还远远不够，因为他还发现海水中需要饱含足够的氧，于是这两个因素一起足够证明这些大型鱼类的高代谢率观点了。

Ninety-nine percent of the blood cells floating in plasma are red blood cells, which carry oxygen from the lungs to the rest of the body and give blood its red color.
