    This is a Neutrophil. Neutrophils 'eat' bacteria. First, plasma proteins called opsonins attach to the bacteria, then the neutrophil attaches to the bacteria and identifies it. The neautrophil then engulfs the bacteria, forming a vacuole. The neutrophil's lyosomes release enzymes and acid into the vacuole, which digest the bacteria. The contents are then dispersed into the cytoplasm.

    The Story of the Neutrophil


    B cells have Ig molecules on their surface, these recognise antigens. When they do, the B cell is activated, and splits myotically into many plasma and memory cells. The plasma cells synthesise specific antibodies which neutralise the toxins. The memory cells have igs just like the irigional cell, so if the antigens return, they can bring about quick production of antibodies (secondary response). This whole response is called the humoral immune response.

    monocytes form macrophages, eosinophils secrete major basic protein which kills parasitic worms
