| Question | Answer |
| Arterial blood vessels: most systemic vessels | Alpha-1 = vasoconstriction (increased SVR) |
| Arterial blood vessels: skeletal muscle vessels | Beta-2 = vasodilation (decreased SVR) |
| SA node | Beta-1 = increased heart rate |
| AV node | beta-1 = increased conduction speed |
| heart: muscle fibers | beta-1 = increased contractility |
| lung: bronchiolar muscle | beta-2 = bronchodilation |
| Lungs: secretory glands | Beta-2: increased secretions |
| kidney (1 of 2) | beta-1: increased renin release |
| Kidney (2 of 2) | Alpha-1: decreased renin release |
| Liver | Beta-2: glycogenolysis & gluconeogenesis |
| Uterus relaxation | Beta-2 |
| Uterus contraction | Alpha-1 |
| Na+/K+ pump | Beta-2 = stimulates Na+/K+ pump (decreases plasma K+) |
| veins | alpha-1 = vasoconstriction (increased preload) |
