Question

1. joanna loves to take long walks in her neighborhood park. recently when she walked, she noticed that the tree leaves and benches were covered in yellow pollen dust. it was not long before joanna developed a cough and a runny nose.

what two systems are working together to maintain homeostasis in this scenario?
a. the immune system and the nervous system.
b. the respiratory system and the immune system.
c. the nervous system and the respiratory system.
d. the immune system and the reproductive system.

Explanation:

When Joanna was exposed to pollen (a foreign substance), her immune system recognized it as a threat. The immune system's response led to symptoms like cough and runny nose. The respiratory system is involved as the pollen enters through the airways (nose and throat), and the immune - respiratory interaction is key here. The immune system tries to eliminate the pollen (as an allergen), and the respiratory system shows the physical manifestations (coughing to expel irritants, runny nose due to increased mucus production as part of the immune - mediated response).

Answer:

B. The Respiratory System and the Immune System.
