Beta2-Receptor Agonists and Antagonists - StatPearls - NCBI - NIH Lungs (bronchioles), blood vessels, and various organs
When stimulated, they increase heart rate and the strength of each beat. In the kidneys, they trigger the release of renin to help regulate blood pressure. Beta-2 ($\beta$2) Receptors: The Great Relaxer beta receptor
These receptors promote relaxation. They dilate the airways to help you breathe easier and widen blood vessels (vasodilation) to improve flow. Beta-3 ($\beta$3) Receptors: The Metabolic Manager
