Adrenaline plays the role of a very important
neurotransmitter. In addition, adrenaline when released into the circulatory system, has
effects on all the major organs in our body.
This happens
when we encounter any stressful situation and to allow the body to be able to deal with
the circumstances, the sympathetic nervous system releases adrenaline to deal with the
stress. Adrenaline is associated with the flight or fight state that we need to get
into to escape from many situations. This has evolved over evolution, as when faced with
predators, the survivors were those who were able to either fight them or run and seek
refuge. To accomplish this, the heart rate increases, the lungs beat faster to provide
more oxygen to muscles and more energy is released from the energy stores we have in our
body.
