In both of these situations, blood glucose levels are low and as a result cellular metabolism slows down considerably.

在这两种情况下，血糖水平都很低，结果就是细胞新陈代谢大大减慢。

Carbon dioxide is a product of this cellular metabolism.

二氧化碳是这种细胞代谢的产物。

The plant-derived system is shown to correct energy imbalance, restore cellular metabolism and protect against the chronic inflammation of the joints, according to the study.

研究显示，这种植物衍生系统能够纠正能量失衡，恢复细胞代谢，并防止关节的慢性炎症。

One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism.

这一功能的一个方面是清除体内由于细胞代谢而积累的废物。

Cellular metabolism produces carbon dioxide and lactic acid, which lowers pH to about 7.2 - now that's compared with a pH of 7.4 in the lungs.

细胞的新陈代谢会产生二氧化碳和乳酸，将pH值降至7。2左右，而肺部的pH值则为7。4。

Blood that enters the pulmonary artery is carried to the lungs. There it undergoes oxygenation, a process in which carbon dioxide (a waste product of cellular metabolism) is exchanged for oxygen from the environment.

氧合血经肺静脉回流至心脏，进入左心房。心房收缩驱动左房血液经二尖瓣进入左室。

And, carbon dioxide and other waste products of cellular metabolism are absorbed from the tissues for transport to the organs of elimination. The blood also transports hormones from endocrine glands to their target organs.

并且，细胞代谢的二氧化碳和其他废料从组织中被吸收以运输到排泄器官。血液还将激素从内分泌腺体运输到它们的靶器官。
