Q 
You give one drug that works on alpha-1 adrenergic receptors to constrict blood vessels in systemic circulation increasing blood pressure. At the same time you give another drug that works on the same receptors only in the heart to slow Ca2+ reabsorption increasing cardiac output. The effect of increased cardiac output and the effect of increased vasoconstriction exaggerates one another leading to an effect that is greater then the effect the drugs would each have if given on their own. This is an example of what?
A. Summation
