Blood on the right side therefore never gets oxygenated, and blood on the left side never gets deoxygenated.

从右心室出来的血液不会被氧化，同样，从左心室出来的血液不会去氧化。

Veins are a passive, more limpy process because it's the bottom number of millimeters of mercury on your blood pressure, and it's the blood that is now deoxygenated.

静脉是一个被动的、更脆弱的过程，因为它是血压的最底层毫米汞柱，现在血液缺氧了。

HbS carries oxygen perfectly well, but when it is deoxygenated, HbS changes its shape, which allows it to aggregate with other HbS proteins and form long polymers that distort the red blood cell into a crescent shape - a process called sickling.

HbS能够很好地携氧，但在脱氧时，HbS会改变其形状，从而使其与其它HbS蛋白聚集形成长链多聚体，进而使红细胞扭曲变形成新月型，该过程称为镰变。
