Beta-1 receptors are found in the heart, and when stimulated will increase herat rate and cardiac contractility. Beta-2 receptors are found on vascular smooth muscle located in the heart and skeletal muscle, and when they are activated, they dilate and decrease SVR.
Associated with vascular smooth muscle are a large number of alpha 1 receptors relative to beta 2 receptors. Activation of these receptors by sympathetic nervous system transmission or drugs will result in vasoconstriction and an increase in peripheral resistance and systemic arterial blood pressure.he adrenergic receptors which subserve the response of the sympathetic nervous system have been divided into two discrete subtypes: alpha adrenergic receptors (alpha receptors) and beta adrenergic receptors (beta receptors).
