血在倒流用英文怎么说

"血在倒流"的英文表达是"blood is flowing backwards"。

这个表达的来源可能是指血液在人体内的正常流动方向是从心脏向外的，但如果血液的流动方向反过来，就好像血液在倒流一样。

例句：

The doctor said the patient's blood was flowing backwards, causing a circulation problem. (医生说病人的血液在倒流，导致了循环问题。)

I could feel the blood rushing to my head as I stood up too quickly. It felt pke my blood was flowing backwards. (我站起来太快，感觉血液涌到了头上。感觉就像血液在倒流一样。)
