👉 The photo depicts the process of infection, illustrating how a pathogen, such as a virus or bacteria, enters and begins to multiply within a host's body. At the center, a cell is shown to be invaded by microorganisms, often visible as tiny particles or structures like viral capsids or bacterial flagella. The surrounding tissue or organ cells appear to be affected, with signs of inflammation—such as swelling, redness, and sometimes pus formation—indicating the immune system's response to the invader. This visual representation highlights the initial stages of infection, from entry to the host's defense mechanisms activating, emphasizing the body's struggle to contain and eliminate the pathogen.
