Asthmatic bronchus

Asthma is a chronic reactive airway disorder that causes episodic airway obstruction. Such obstruction results from bronchospasms, increased mucus secretion, and mucosal edema. It’s a type of chronic obstructive pulmonary disease, a group of lung diseases characterized by increased airflow resistance.

Alveolar changes in ARDS

Acute respiratory distress syndrome (ARDS) is a form of pulmonary edema that can quickly lead to acute respiratory failure. Also known as shock lung, stiff lung, white lung, wet lung, or Da Nang lung, ARDS may follow direct or indirect injury to the lung. However, diagnosis is difficult and death can occur within 48 hours of onset if ARDS isn’t promptly diagnosed and treated.

In phase 1, injury reduces normal blood flow to the lungs. Platelets aggregate and release histamine (H), serotonin (S), and bradykinin (B).
