Question

1. choose the best answer. which of the two types of white blood cells actually destroys pathogens? t cells p cells w cells b cells 7) select all that apply. which three ways does the respiratory system fight off pathogens? capturing them in cilia in the nasal passages coating them with mucus so they can be destroyed in the stomach shutting down other systems releasing acid in the body coughing and sneezing to remove them

Explanation:

1. T - cells help coordinate the immune response and can directly kill infected cells. B - cells produce antibodies that can mark pathogens for destruction. P - cells and W - cells are not types of white - blood cells relevant here.
2. The respiratory system has several defense mechanisms. Cilia in the nasal passages can trap pathogens. Mucus coats pathogens so they can be swallowed and destroyed in the stomach. Coughing and sneezing are ways to physically remove pathogens. Shutting down other systems and releasing acid in the body are not typical respiratory - system pathogen - fighting mechanisms.

Answer:

1. A. T cells, D. B cells
2. A. capturing them in cilia in the nasal passages, B. coating them with mucus so they can be destroyed in the stomach, E. coughing and sneezing to remove them
