内皮分解的

Hemoglobin in the blood is made into unconjugated bilirubin in the reticuloendothelial system, then into conjugated bilirubin in the liver, which is in turn made into urobilinogen in the intestines.

血液中的血红蛋白在网状内皮系统被分解成未结合胆红素，然后在肝脏中被转化为结合胆红素，再进入肠道，转化为胆原。

The gaseous monoxides nitric oxide and carbon monoxide, generated within the blood vessel wall, have been identified as important cellular messengers involved in the regulation of intracellular cGMP levels, platelet aggregation and smooth muscle relaxation, The mechanism by which carbon monoxide activates soluble guanylyl cyclase is similar to that of nitric oxide, and involves binding and dislocation of its heme-iron to induce a conformational change and activation of the catalytic site of guanylyl cyclase.

一氧化氮是体内最重要的气体信使分子，不仅是维持血管正常舒缩功能的重要介质，而且还有抑制单核细胞及血小板与内皮的粘附、聚集、抑制血管平滑肌细胞的增殖等作用。近年研究表明，内源性一氧化碳是体内另一个重要的气体信使分子，它是由血红素氧合酶氧化分解血红素产生的，具有与一氧化氮相似的生理功能。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
