By acting on alpha 1 adrenergic receptors it produces
vasoconstriction at vascular beds so letting the flowing blood

exert more force on walls of blood vessels and thereby its
increasing pressure
By stimulating Beta 1 adrenergic receptor that is present on

e; positive
chronotropic effect) , both of which increases Cardiac Output
...

By affecting beta 2 adrenergic receptor it produces the
bronchodilation of bronchial smooth muscle cells and reversing
the respiratory collapse
...

Epinephrine also has effects on glycemia as it activates beta2
adrenergic receptors on liver and leads to increase availability
of glucose through Glycogenolysis and Gluconeogenesis
