Questions: Question 9 0.5 pts This figure shows the result of interaction of RBC antigens ( A antigens) with the antibody against the RBC antigen (anti-A antibodies). This result is called (d) coagulation transfusion hemostasis agglutination

Solution Steps

The prompt describes a reaction between red blood cell (RBC) antigens and their corresponding antibodies (anti-A antibodies). The image shows clumping of red blood cells.

• Coagulation: This refers to blood clotting, a complex process involving platelets and clotting factors, not the clumping of RBCs by antibodies.

• Transfusion: This is the process of transferring blood from one individual to another, not the reaction being described.

• Hemostasis: This refers to the process of stopping bleeding, involving vasoconstriction, platelet aggregation, and coagulation. It's a broader term than the specific reaction in question.

• Agglutination: This is the clumping of cells (like bacteria or red blood cells) caused by an antibody reacting with an antigen on the cell surface. This matches the description and the image provided.

Final Answer: The result is called agglutination.
