The parasite that causes malaria, though, can only complete its life cycle in normal, round red blood cells.

然而，导致疟疾的寄生虫只能在的圆形细胞中完成其生。

Even though Respirocyte is six times smaller than a normal red blood cell, it's able to carry 236x more oxygen and carbon dioxide!

管呼吸细胞比细胞小六倍，但它能够携带 236 倍多的氧气和二氧化碳！

Carriers are less susceptible to malaria, because they make some sickled red blood cells, but they make enough normal red blood cells that they aren't negatively affected by sickle cell anemia.
