章 389: Exchanging Skills

Fu Ning didn't understand all of what he had read.

He didn't know what a cell was, all the more the red blood cells.

He looked at the chart below the words he had just read.

Whoever wrote the book was nice enough to explain how to read the chart.

Then there was another statement that caught his attention.

"This one—Most of the time, being Rh-negative has no risks. But during pregnancy, being Rh-negative can be a problem if your baby is Rh-positive. If your blood and your baby's blood mix, your body will start to make antibodies that can damage your baby's red blood cells. This is known as Rh sensitization…. Can you explain this to me?" Fu Ning turned to Song Jia.
