Bronchial spasm: Your airway is made of tubes called bronchi. The smaller tubes at the ends are called bronchioles. They are lined with muscles that can constrict (squeeze) or dilate (expand). Anything that makes the bronchioles constrict (infection, allergies, etc.) will make you wheeze.

Airway obstruction: Wheezing occurs when airway narrowing forces air to speed up as it passes the obstruction. Its the same deal as whistling. Higher airspeed causes the airway to vibrate generating sound. Anything that narrows the airway causes wheezing. In asthma that's airway muscle contraction (bronchospasm) & globs of thick mucous in the airway. Foreign bodies, tumors, & external compression also cause wheezing.

Physical sign: A symptom is what a patient describes. A sign is what a doctor finds. Sometimes they can be the same thing. A wheeze is a sign that indicates spasm or tightening of airways. This makes it hard to breathe out. So the patient has to force the air out. The velocity increases and causes a musical tone that can be heard with a stethoscope. It happens with asthma, emphysema, and other copd.
