The small, circular/spherical structure labeled "a" is an antigen in the immune complex reaction shown in Figure 19.1. Antigens are foreign substances that trigger an immune response in the body, and in this case, they are being targeted by antibodies. Complement, neutrophils, and mast cells are all components of the immune system but are not represented by the small structure labeled "a" in the figure.
