increasing blood flow to all cells, therefore delivering glucose faster

Detailed explanation-1: -Thus, an additional and important action of adrenaline is to increase plasma glucose by promoting glycogenolysis in the liver and skeletal muscle, liver gluconeogenesis and reduction of glucose uptake by tissues such as skeletal muscle via activation of 1‐ and 2‐adrenoceptors (Moratinos et al., 1986).
Detailed explanation-2: -Hence, epinephrine causes constriction in many networks of minute blood vessels but dilates the blood vessels in the skeletal muscles and the liver. In the heart, it increases the rate and force of contraction, thus increasing the output of blood and raising blood pressure.
Detailed explanation-3: -Adrenaline, also called epinephrine, helps your body react more quickly to a threat. It makes the heart beat faster, increases blood flow to the brain and muscles, and stimulates the body to make sugar to use for fuel.
Detailed explanation-4: -Epinephrine augments hepatic glucose production by stimulating glycogenolysis and gluconeogenesis. Although its effect on glycogenolysis rapidly wanes, hyperglycemia continues because the effects of epinephrine on gluconeogenesis and glucose disposal persist.
