Answer #1

He will feel little nervous before presentation and Catecholamines are secreted. Catecholamines are hormones produced by the adrenal glands, which sit on top of the kidneys. It can serve as neurotransmitters, transferring signals from neuron to neuron, as well as hormones, which regulate physiological functions such as your heartbeat and breathing rate.

Via the hypothalamus and the sympathetic nervous system, psychological stress stimulates the adrenal medulla to secrete the two catecholamines, epinephrine (adrenaline) and norepinephrine (noradrenaline), into the bloodstream. This rapid defence reaction prepares the body for battle.
