Each label describes an aspect of either coagulation or agglutination, which are illustrated in the photographs. drag and drop each label onto the appropriate photographs.

The first picture represents platelet aggregation (primary hemostasis) and the second picture represents coagulation (secondary hemostasis).

Hemostasis: it concern both pictures, because there's primary and secondary hemostasis
Fibrin: it concerns the second picture, we can see the fibrin mash in yellow surrounding red blood cells.
Blockage of a tear in a vessel wall, blockage of small vessels: it may concern the primary hemostasis but it is not represented in the first picture.
Role of thrombin: its role is to transform fibrinogen to fibrin to form the fibrin mash, so we can associate it with the second picture.
Transfusion reaction, antigen and antibodies: it is not represented in these pictures
Agglutination (of platelets): it concerns the primary hemostasis (the first picture).
RBC caught in protein mash: which is well represented in the second picture (fibrin is a protein)
Coagulation: By definition is the activation of fibrinogen to fibrin to form a fibrin mash, which is represented in the second picture.

Ithink the answer is c. i’m not sure though i’ll notify you when i have an exact answer!
