Which endocrine gland secretes hormones that the body adapt to stressful situations, reduce inflammation, and prepare the body for physical stimulation?

Adrenal glands

The adrenal glands consist of different parts which produce different types of hormones, most commonly ones that help the individual cope with stress, both long-term and short-term. These hormones include epinephrine (adrenaline), norepinephrine (noradrenaline), and cortisol. For short-term stress, hormones (epinephrine and norepinephrine) are released to prepare the body for physical exertion (i.e. in fight-or-flight situations). On the other hand, cortisol helps a person cope with long-term stress and this hormone has also been known to reduce inflammation as well. 

Other hormones produce by the adrenal glands include those essential for regulating fluid and electrolyte balance, and glucose in the body.
