Airborne allergens can trigger an allergic response in the body, leading to symptoms like sneezing, coughing, and itchy eyes. The body's defense against this involves producing antibodies like IgE to target and neutralize the allergen. If these defense tactics fail, the body may activate an inflammatory response, causing more severe symptoms like wheezing and difficulty breathing, which may require medical intervention such as antihistamines or corticosteroids.

The nose serves as the first line of defense by filtering and trapping airborne pathogens, dust, and allergens through its mucous membranes and fine hairs called cilia. These structures help prevent harmful particles from entering the respiratory system. Additionally, the nasal passages contain immune cells that can initiate an immune response against pathogens. This filtering and immune activity play a crucial role in protecting the body from infections and maintaining overall respiratory health.
An immune response is part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically toward that pathogen.
The Second Line of defense is mainly called the Inflammatory Response. Some may say the immune response is the second layer too. The Second Line of Defense also includes leukocytes such as macrophages.

The nickname "Screaming Eagles" for the 101st Airborne Division symbolizes their fierce and fearless reputation in combat. During the Battle of the Bulge, the 101st Airborne Division played a crucial role in defending Bastogne against a much larger German force. Their refusal to surrender and the defiant response "Nuts" to a German surrender demand showcased their determination and resilience in the face of overwhelming odds. This moment became a symbol of American courage and defiance during World War II.
Eosinophils are the granular leukocytes that stain red. They are important elements of the body's immune defense against pathogens and allergens.
The third line of defense against pathogens in the body is called the adaptive immune response. This response involves the activation of specific lymphocytes, such as T cells and B cells, which recognize and target specific pathogens. Unlike the innate immune response, the adaptive response develops memory for previously encountered pathogens, allowing for a faster and more effective response upon re-exposure. This system is crucial for long-term immunity and protection against various diseases.
The process is called the immune response. It involves the activation of various cells and molecules, including white blood cells, antibodies, and cytokines, to identify and eliminate pathogens, foreign substances, and damaged cells. This complex system not only protects the body from infections but also plays a role in responding to allergens and tissue injuries. The immune response can be innate, providing immediate defense, or adaptive, developing a targeted response over time.
