Bronchial asthma is described as a reversible obstrution of the airway due to spasm of the smooth muscle of the
smaller bronchi and bronchioles. The mucous membrane lining the respiratory tract can also become irritated causing p
roduction of thick mucous that plugs the smaller air passages worsening the attack. The patient will have difficulty exhaling and will have an anxious appearance. Bronchial asthma can be of a psychosomatic origin but normally there are two varieties.Extrinsic Asthma
