MICROANATOMY

Detailed explanation-1: -About bronchodilators Bronchodilators are a type of medication that make breathing easier. They do this by relaxing the muscles in the lungs and widening the airways (bronchi). They’re often used to treat long-term conditions where the airways may become narrow and inflamed.

Detailed explanation-2: -E promotes air flow through the bronchioles by causing relaxation of their smooth muscle (bronchodilatation) (2), and thus allows for increased alveolar ventilation. The increased blood flow through the lungs (see above) and the increased alveolar ventilation ensure maximal oxygenation of blood.

Detailed explanation-3: -Albuterol is an inhaled short-acting beta-2 agonist that stimulates beta-2 receptors on the surface of airway smooth muscle. The increased sympathetic tone causes the relaxation of airway smooth muscle, which causes dilation of the bronchi and bronchioles, reducing airway resistance.

Detailed explanation-4: -Bronchodilators are medicines that relax (dilate) the airways of the lungs (bronchial tubes). This makes it easier for a person to breathe in more air.
