A set of teaching tools

Abstract

1. The material of the article to which this design relates is synthetic resin. 2. The article to which this design relates is a set of teaching tools that can be used to learn about ABO blood types and RhD blood types. 3. Teaching tool A represents red blood cells, teaching tool B represents type A antigens, teaching tool C represents type B antigens, teaching tool D represents RhD antigens, teaching tool E represents anti-type A antibodies, teaching tool F represents anti-type B antibodies, and teaching tool G represents anti-RhD antibodies. 4. The article to which this design relates is designed to easily explain the phenomenon of red blood cells and the antigens present on their surfaces reacting with antibodies in serum. 5. Reference Figures 1 to 3 show the product in use. Reference Figure 1 shows that when type B red blood cells are reacted with a type A person, the anti-B antibodies in the type A serum and the type B red blood cells agglutinate. Reference Figure 2 shows that when type A red blood cells are reacted with a type B person, the anti-A antibodies in the type B serum and the type A red blood cells agglutinate. Reference Figure 3 shows the RhD phenomenon, where red blood cells with RhD antigens on their surface agglutinate with anti-RhD antibodies.
