How does noradrenaline act on adrenergic receptors to raise blood pressure?

Noradrenaline strongly stimulates alpha and moderately stimulates beta-1 receptors, causing generalised vasoconstriction (except indirect coronary dilation through increased oxygen consumption), increased peripheral resistance and stronger myocardial contraction, with an increased heart rate in the absence of vagal inhibition, thereby raising systolic and diastolic blood pressure.
