Answer :
Final answer:
Obstructive diseases like emphysema and asthma, as well as obstructive sleep apnea, can cause an obstructed airway due to various factors like inflammation and tissue relaxation. Swelling of body tissues in general can be a result of allergic reactions, infections, or irritants, contributing to airway constriction and breathing difficulties.
Explanation:
Obstructive diseases and conditions such as emphysema, asthma, and pulmonary edema can cause an obstructed airway. In emphysema, the destruction of alveoli walls reduces gas exchange surface area, while in asthma, inflammation triggers airway obstruction. These conditions lead to increased air trapping and difficulty in breathing.
Other conditions such as obstructive sleep apnea can also obstruct the airway. Factors like excessive relaxation of throat muscles or obesity can contribute to airway blockages during sleep, affecting breathing.
Causes of airway constriction and swelling can include allergies, infections, irritants, or physical obstructions. Swelling of body tissues in general can result from inflammatory responses to various triggers, leading to constriction and restricted air passages.
