Blood Typing

 

The ABO blood typing system is dependent on the presence or absence of different antigens on the cell membranes of the erythrocytes. Individuals with A, B, AB, or O blood types have different antibodies, or none at all, in their plasma depending on their blood type. For a successful blood transfusion to occur, the compatibility of the recipient’s and the donor’s blood must be determined. Some people are universal blood donors, while some people are universal blood recipients.

 

Watch and Listen

 

You have the choice of viewing an animation that explains the difference between each of the blood types or looking at a slide show. Both provide an opportunity for a self-assessment of your understanding. If you are still unclear about blood typing, or you had difficulty with the

self-assessments, go to page 296 in the textbook for a written explanation. Or you can view the other media.

 

Animation

 

This animation explains the difference between each blood type. It also indicates what happens when different blood types mix.

 

After watching the animation, answer the five questions relating to ABO blood typing found below the animation. When you have completed the questions, click the “Submit Answers” button to get immediate feedback. If you answered a question incorrectly, the feedback will help you understand the correct response.

 

This slide show will walk you through the blood-typing process.
