C) Incorrect. While asthma involves inflammation, it is not typically an acute respiratory infection.

A) Incorrect. Asthma is not primarily caused by bacterial infections.

B) Incorrect. While excess mucus can contribute to asthma symptoms, it is not the primary mechanism.

C) Correct. Asthma is characterized by chronic inflammation of the airways and increased reactivity, leading to airway narrowing and symptoms.

D) Incorrect. Asthma primarily involves airway inflammation and narrowing, not a lack of oxygen in the bloodstream.

A) Incorrect. Mast cells do not release hormones that relax airway muscles; they are involved in inflammation.

B) Correct. Mast cells release inflammatory substances in response to allergens, leading to bronchoconstriction and inflammation in asthma.

C) Incorrect. Mast cells are not primarily involved in clearing excess mucus from the airways.

D) Incorrect. Mast cells do not produce antibodies to protect against asthma attacks.

A) Incorrect. Asthma leads to airway narrowing, not widening.

B) Incorrect. While chronic inflammation can lead to airway remodeling over time, it does not make the airway walls more rigid in the acute phase.

C) Correct. Asthma is characterized by inflammation and narrowing of the airways, which can lead to symptoms like wheezing and difficulty breathing.

D) Incorrect. Asthma does affect the structure of the airways, primarily through inflammation and airway remodeling in the long term.

A) Incorrect. Eosinophils do not release hormones that relax airway muscles.

B) Incorrect. Eosinophils are not primarily involved in antibody production in asthma.

C) Incorrect. Eosinophils are not responsible for clearing excess mucus from the airways.

D) Correct. Eosinophils are white blood cells that contribute to inflammation and airway damage in asthma by releasing inflammatory substances.

A) Incorrect. Bronchial smooth muscle is involved in asthma, particularly in airway constriction.

B) Correct. In asthma, bronchial smooth muscle contracts and narrows the airways, contributing to symptoms like wheezing and shortness of breath.

C) Incorrect. Bronchial smooth muscle's primary role in asthma is not to clear mucus from the airways.

D) Incorrect. Bronchial smooth muscle does not release antibodies to protect against asthma attacks.

A) Incorrect. Bacterial infections are not the primary cause of asthma; it is more related to inflammation and airway hyperreactivity.

B) Incorrect. Genetics can indeed play a role in the development of asthma.

C) Correct. Environmental factors, including allergens and irritants, are significant contributors to asthma development and exacerbation.

D) Incorrect. While emotional stress and anxiety can exacerbate asthma symptoms, they are not the sole triggers of the condition.
