TRANSPORT IN PLANTS AND ANIMALS BLOOD GROUPS AND BLOOD TRANSFUSION Lesson objectives; By the end of the lesson the learner should be able to explain the reaction between antigen and antibobody

Blood groups Types of blood group systems include; ABO system (e.g. blood type A, B, AB & O), Rhesus factor (e.g. rhesus positive & rhesus negative), Types of blood group systems include; ABO system (e.g. blood type A, B, AB & O), Rhesus factor (e.g. rhesus positive & rhesus negative),

Blood transfusion During blood transfusion the donor’s antigen A & B on RBC as well as the antibody a & b in the plasma of the patients blood are considered, Blood type A has antibody b in the plasma, Blood type B has antibody a in the plasma, Blood type AB lacks both antibody a & b in the plasma, hence universal recipient, Blood type O has both antibody a & b in the plasma, During blood transfusion the donor’s antigen A & B on RBC as well as the antibody a & b in the plasma of the patients blood are considered, Blood type A has antibody b in the plasma, Blood type B has antibody a in the plasma, Blood type AB lacks both antibody a & b in the plasma, hence universal recipient, Blood type O has both antibody a & b in the plasma,
