This is the right response. d) “Allergic reaction of the mast cells in the lungs” The activation of mast cells in the lungs is a common cause of asthma, which is frequently linked to allergic reactions. Mast cells release chemicals, such as IgE antibodies and chemicals like seratonin and histamines, in response to allergens or irritants. These substances can cause bronchoconstriction, airway inflammation, and the usual symptoms of asthma. People with asthma experience an allergic reaction in their airways when they are exposed to allergens (like dust mites, pollen, or pet dander) or irritants (like smoke or strong odors).

The diagram below illustrates how the pharynx sends air through the glottis to the larynx:

The respiratory disease known as bronchitis results in inflammation of the bronchioles, the lungs’ tiny airways. It primarily affects infants and young children and is most frequently brought on by a viral infection, such as respiratory syncytial virus (RSV). Wheezing, coughing, shortness of breath, and breathing difficulties—which can be quite severe in certain situations—can be brought on by inflammation of the bronchioles. A physical examination and the patient’s symptoms can be used to diagnose bronchiolitis, which can then be verified by a chest X-ray or other tests. Supportive care, including fluids, humidified air, and symptom-relieving medications, is usually used to treat bronchiolitis. Hospitalization may be required in certain situations, particularly for young children and infants who are more likely to experience complications.

Lungs are covered by pleural membranes. The ‘pleura’ are thin, double-layered membrane sacs that cover the lung.

The trachea is a tube made of membranes. It is made up of smooth muscle and dense, regular tissue that are strengthened by 15–20 C-shaped pieces of cartilage. Another name for it is a windpipe. D is therefore the right choice.

There are three ways that carbon dioxide can move through the blood. It can dissolve straight into the blood, bind to hemoglobin or plasma proteins, or change into bicarbonate. The bicarbonate system is responsible for the majority (roughly 70%) of carbon dioxide transportation. Red blood cells absorb carbon dioxide. Option C is therefore correct.
