In brief: 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.

In brief: 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.
