How would a drug that is a bronchodilator cause changes to A) areas of the conducting zone, and B) respiratory zone performance

Expert Solution

Bronchodilators are a type of medication that make breathing easier 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, such as: asthma, a common lung condition caused by inflammation of the airways.

The conducting zone of the respiratory system is made up of the nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles; their function is to filter, warm, and moisten air and conduct it into the lungs.For the lungs to function properly, the conducting airways must be open to the respiratory zone where gas exchange occurs.

so in the constriction of lung airways like in COPD,The flow of air into the respiratory zone of lung is limited that cause reduced respiratory function Bronchodilators treat bronchospasms by affecting the muscles around the airways to relax. When the muscles are relaxed, the airways become wider, which allows more air to travel in and out of the lungs.

The. respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoliIn respiratory zone Their action rapidly opens the airways, letting more air come in and out of the lungs.There by increases the Gas exchange through Alveoli. As a result, breathing improves. Bronchodilators also help clear mucus from the lungs
