Blood is packed with red blood cells.
Even though all human blood might look the same, there are actually different kinds called blood types.
Blood types are based on special markers on the surface of red blood cells. These markers, known as antigens, are made from sugars, proteins, and other molecules, and everyone has their own unique set.
There are several systems used to classify blood types...
The best-known are the ABO and Rh blood types, which are very important when it comes to safely giving someone a blood transfusion.
Today, we took a closer look under a microscope to see what happens when we mix blood from different ABO blood types!
