Heart plays a major role in the circulatory system with supplying blood to all the different parts of our body. Pumping of the heart muscles or cardiac muscles is stimulated by the pacemaker cells, which occupy 1% of the heart muscle cells, while other 99% are contractile cells. Sino atrial(SA) node plays a major role as a natural pacemaker by firing action potentials on its own for contraction.
Adrenal gland, also called as the suprarenal gland, is one of the major glands of the endocrine system. It produces two hormones, such as adrenaline/epinephrine and cortisol. These hormones aid in dangerous situations in flight or fight response. The other two hormones, nor-adrenaline/norepinephrine and dopamine, aid in increased stress response.
