Final answer:
The immune system and respiratory system collaborate to protect the body from pathogens and harmful substances. During an infection, the immune system responds to pathogens in the respiratory system. Overall, they work together to maintain respiratory health.
Step-by-step explanation:
In healthy individuals, the immune system and respiratory system collaborate to protect the body from pathogens and harmful substances. The respiratory system contains protective mechanisms such as nasal hairs and mucus that trap particles, bacteria, and viruses, preventing their entry into the body. Additionally, the immune system plays a role in clearing out any pathogens that manage to reach the respiratory system, preventing infections.
During an infection, the immune system responds to the presence of pathogens in the respiratory system. Immune cells, such as macrophages, neutrophils, and T cells, target and eliminate the pathogens to control the infection. The immune system also triggers an inflammatory response, which can lead to symptoms such as coughing, sneezing, and mucus production, as the body tries to expel the pathogens.
Overall, the immune system and respiratory system work together to protect the body from infection and maintain respiratory health.
