What would be true if fighting an infection was like fighting a war?
A. T Cells would be holding the enemy back (bacteria), while B Cells and lymphocytes ready the weapons (antibodies) B. T Cells would be readying the weapons (antibodies), while B Cells and lymphocytes hold the enemy back (bacteria) C. T Cells and B Cells will both slowly start the process of preparing to fight the enemy (bacteria)
When a body is attacked by bacteria the inherent immune system acts to protect the body automatically. When the immune system is acquired, not natural, it must learn to recognize the enemy (bacteria). To fight it, T cells help activate B cells to secrete antibodies for destroying ingested microbes. They also help activate T cells to kill infected cells.
So if an analogy is formed between the immune system and war, both T cells and B cells are fighting, but T cells are facilitators, perhaps with an Intelligence function, rather than a set of weapons. B cells are like the infantry; they need direction and the T cells 'tell' them what to attack and where.
