Narrowing of the airways, such as occurs during asthma attacks and can be reversed by use of a reliever inhaler. May be prevented by use of a preventer inhaler

constriction of the bronchial airways in the lungs, causing shortness of breath, tightness in the chest, coughing, and wheezing

Constriction of airways that makes breathing difficult. Especially dangerous in combination with mucus plugging.

describes the narrowing of the airways in the lung. This may be the result of natural processes, or of a progressive disease state

The reduction in the diameter of the bronchi, usually because of squeezing of the smooth muscle in the walls. This reduces the space for air to go through and can make breathing difficult.

A term that refers to the tightening of muscles around the airways.

Constriction of the smooth muscle in airways in the lungs due to exposure to irritant chemicals or to an immunological reaction involving release of inflammatory mediators.

Narrowing of the air passages in the lungs.

A narrowing of the airway passages.

A process when the muscles that are wrapped around the airways tighten, and squeeze the airways closed. This is one of the ways that asthma causes trouble breathing. The bronchoconstriction part of asthma is treated with bronchodilator medicines (also known as reliever or quick relief medicines).

The narrowing of breathing passages known as the bronchi, which lead from our windpipe (trachea) into our lungs.

Narrowing of the airways of the lungs.

This is when the muscles that wrap the airways constrict tighter and tighter, pinching the airways closed.

When the muscle that wraps around the bronchi constricts or tightens, the airways narrow, resulting in bronchoconstriction (bronchospasm). Inflammation (swelling) of the inner lining of bronchi can also cause airway narrowing. Airway narrowing makes it hard to move air into and out of the lungs, causing chest tightness and wheezing.

Tightening of the muscles surrounding the bronchi; opposite of bronchodilation.

Constricting of the air passages into the lungs.

Narrowing of the air passages through the bronchi of the lungs AN bronchodilation

The state in which bronchial smooth muscle contracts and the airways narrow.

Constriction of the bronchi

Bronchoconstriction means the muscles surrounding the airways contract and tighten (constrict), squeezing and narrowing the airways. Bronchoconstriction is one cause of asthma symptoms.

Bronchoconstriction is the constriction of the airways in the lungs due to the tighting of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath. Bronchoconstriction can also be due to an accumulation of thick mucus.
