Which of the following is not a first line non-specific defense against pathogens?

What type of 2nd line defense occurs when you get a splinter and your skin becomes red and swollen?

When you are infected specifically by pneumonia bacteria, your which line of defense attacks this pathogen specifically using T and B cells?

This virus infects your T cells, thus eliminating your 3rd line defense system

In the second line defense, the function of the these white blood cells (macrophages, dendritic cells and neutrophils) is to patrol certain areas and

The function of the B-cell is to learn the shape of the pathogen antigen and create these that will surround the invader

After you have successfully defeated a virus or bacteria, your body makes these cells so that your response same pathogen next time is faster and stronger

When a DEAD pathogen is injected into your body, your T cells and B cells respond by attacking the antigen and making antibodies. This process is called
