Question: 1 / 20

Beta 2 receptors are predominantly associated with which physiological response?

Cardiac stimulation

Smooth muscle contraction

Bronchodilation

Beta-2 receptors are primarily located in the smooth muscle of the airways, as well as in blood vessels and the uterus. When these receptors are activated, particularly by agents like epinephrine, they lead to the relaxation of smooth muscle. This physiological response is known as bronchodilation, which is the widening of the air passages in the respiratory system. This action facilitates easier airflow, making it particularly important in medical situations involving conditions such as asthma or chronic obstructive pulmonary disease (COPD).

Bronchodilation can help alleviate symptoms of bronchoconstriction, which is why medications that target beta-2 receptors are often used as bronchodilators in clinical settings. This response is crucial in emergency and pre-hospital care, emphasizing the importance of understanding the role of beta-2 receptors in respiratory physiology.
