Final answer:
Macrophages are considered the most effective antigen presenting cells among phagocytes. They can activate T-cells by presenting antigens. Neutrophils, eosinophils, and basophils do not have the same level of antigen-presenting capability.
Step-by-step explanation:
The best antigen presenting cells among the phagocytes are macrophages. Macrophages, along with dendritic cells and B cells, have the unique ability to present antigens to T-cells and initiate an adaptive immune response. Antigens are substances that can induce an immune response, and the presentation of antigens is a crucial step in the activation of T-cells, which play a central role in the immune response.
Neutrophils are also phagocytic, and they are often considered the first responders to infection due to their abundance and rapid response. However, they are not as efficient in antigen presentation as macrophages are. Neutrophils are known to produce cytokines and help in the immediate defense against pathogens but have a limited role in presenting antigens to T-cells.
Eosinophils and basophils also have roles in immune responses; eosinophils primarily deal with parasitic infections, and basophils are involved in allergic responses. However, neither eosinophils nor basophils are known for their ability to present antigens effectively.
