Question

drag each tile to the correct box. match the different responses of the body to an antigen attack to their appropriate systems. innate immune system integumentary system lymphatic system adaptive immune system phagocytosis of antigens by macrophages production of antibodies against the antigen drainage of fluid containing antigens by capillaries protective barrier covering internal organs

Explanation:

1. Phagocytosis of antigens by macrophages: The innate immune system provides immediate, non - specific defense. Macrophages performing phagocytosis is a key part of the innate immune response.
2. Production of antibodies against the antigen: The adaptive immune system responds to specific antigens and produces antibodies (by B cells) to target those specific antigens.
3. Drainage of fluid containing antigens by capillaries: The lymphatic system is responsible for draining interstitial fluid (which may contain antigens) through lymphatic capillaries.
4. Protective barrier covering internal organs: The integumentary system (skin, hair, nails, etc.) acts as a physical protective barrier against antigens and other foreign substances.

Answer:

• "phagocytosis of antigens by macrophages" → innate immune system
• "production of antibodies against the antigen" → adaptive immune system
• "drainage of fluid containing antigens by capillaries" → lymphatic system
• "protective barrier covering internal organs" → integumentary system
