Zahaire just learned she has an upper respiratory bacterial infection. Explain how Zahaire's immune system will likely respond to the infection.
What will be an ideal response?
The front line of defense in the immune system are the white blood cells, or leukocytes, which come in two types: B-cells, which mature in the bone marrow, and T-cells, which mature in the thymus. Zahaire's B-cells and T-cells will activate in response to the bacterial invader and proceed to multiply rapidly to mount a counterattack. B-cells respond to specific antigens and produce antibodies that circulate in the blood, while T-cells (or microphages) circulate through the blood and lymph systems in an effort to engulf the antigens. The entire immune response is an intricate process that involves multiple systems and will ultimately destroy the antigens in Zahaire's body. GRADING RUBRIC: 10 points.
