Skyler takes a medication for asthma, known as a ?2 agonist, to cause bronchodilation. Determine why this drug should have no effect on his heart rate
What will be an ideal response?
?2 agonists bind ?2 receptors on the smooth muscle of the airways and cause bronchodilation to improve breathing for those with asthma. Skyler should not experience an increase in heart rate when he takes his asthma medication since a different type of beta receptor, known as a ?1 receptor, is located in the plasma membranes of cardiac muscle cells as well as certain cells of the kidney and adipose tissue.
