Which two body systems include nose hairs as a defense mechanism against pathogens?

• A. Integumentary and Muscular
• B. Integumentary and Immune
• C. Respiratory and Digestive
• D. Skeletal and Nervous

Answer: (B)

Nose hairs, also known as vibrissae, play a crucial role in protecting the respiratory system from pathogens and foreign particles. They are part of the integumentary system, which includes the skin, hair, and nails, serving a protective function by trapping dust, allergens, and microbes that could enter the body through the nasal passages. The immune system is responsible for identifying and combating pathogens. While nose hairs themselves are not immune cells, they serve as the first line of defense by preventing harmful particles from reaching deeper parts of the respiratory system where more specialized immune responses are activated. This interaction highlights how the integumentary system contributes to the overall function of the immune system, providing a physical barrier to limit exposure to pathogens. Other options do not correctly pair the systems that relate directly to the function of nose hairs. For example, the muscular system does not play a role in this defense mechanism, while the digestive system is primarily involved in processing and breaking down food and does not utilize nose hairs as a defense. Similarly, the skeletal and nervous systems do not have a direct correlation with the protective function of nose hairs.
