Beta-Adrenergic Receptors

Distribution

Receptor Distribution Overview

  • β1 Receptors (Blue)
    • Heart: Increase heart rate and contractility
    • Kidneys: Stimulate renin release → activates RAAS → raises blood pressure
  • β2 Receptors (Green)
    • Lungs: Bronchodilation
    • Vascular Smooth Muscle: Vasodilation
    • Liver: Glycogenolysis and gluconeogenesis
    • Skeletal Muscle: Tremor, increased potassium uptake
    • Uterus: Relaxation (tocolytic effect)
 An educational medical illustration tailored for clinical pharmacists showing the distribution of beta adrenergic receptors in the human body. The image should depict a simplified human figure with labeled organs and tissues where beta-adrenergic receptors are found. Highlight beta-1 receptors primarily in the heart and kidneys. Highlight beta-2 receptors in the lungs, vascular smooth muscle, liver, skeletal muscle, and uterus. Use color coding: blue for beta-1 receptors and green for beta-2 receptors. Include clear labels and arrows pointing to each organ or tissue. Style should be professional, infographic-like, and easy to understand for pharmacists.
