Question: 1 / 400

Which body system is primarily affected by a Beta 2 blocker?

Cardiovascular system

Respiratory system

Beta 2 blockers primarily target the beta-2 adrenergic receptors, which are predominantly found in the smooth muscle of the respiratory tract. When these receptors are activated, they facilitate bronchodilation, allowing for easier airflow in and out of the lungs. Therefore, medications that act as beta-2 blockers are often used in the treatment of respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD).

While beta-1 receptors primarily affect the cardiovascular system by influencing heart rate and contractility, in the context of beta-2 blockers, the respiratory system is the primary target for their action. Beta-2 receptors also play a role in other systems, including the nervous and digestive systems, but their most significant impact is observed in the respiratory system, making it the correct answer in this scenario.
