Question

Quizplus · Accepted Answer

Bronchodilators work by relaxing the smooth muscle cells in the airways, allowing for improved airflow and easier breathing during an asthma attack. This is in contrast to bronchoconstrictors, which would cause smooth muscle cells to contract and worsen the attack. The diaphragm is not directly affected by bronchodilators, as its role is to contract and expand to help with breathing. The alveoli are tiny air sacs in the lungs that are not affected by bronchodilators, as they are not involved in the constriction or relaxation of the airways.
