Rhesus Factor

The video explains blood types, focusing on the Rh factor, a protein on red blood cells. Most people are Rh positive, meaning they have this antigen, while 15% are Rh negative. If Rh negative individuals receive Rh positive blood, their immune system attacks the foreign antigen, causing complications. This reaction is particularly concerning for Rh negative pregnant women. If their baby is Rh positive, the mother's immune system may produce antibodies against the baby's blood cells, leading to health issues. To prevent complications, pregnant women are routinely tested for the Rh factor.
