At the SA node of my heart the epinephrine was increasing the autorhythmicity of my pacemaker therefore causing an increase in my heart rate (Genetic Science Learning Center, 2016). The AV node which is located in between the tissues of the heart was making sure that there were normal electrical impulses traveling throughout my heart (McKinley, 2016). On the other hand, this vasodilation was decreasing the general systemic resistance to blood flow. My internal organs were experiencing vasoconstriction due to the fact that my body was experiencing stress and was more focused on the vasodilation of my upper extremities. My internal organs did not to be digesting food at this time because of the situation that I was in. During, the vasoconstriction of my internal organs the arterioles were constricting and my precapillary sphincters were closing (McKinley, 2016). However, the vasoconstriction in my internal organs that I was experiencing caused my blood pressure to increase and therefore resulting in increased perfusion of blood throughout my body (McKinley,
