Solution

Adrenaline is secreted by adrenal gland.

Explanation:

Adrenaline (also called epinephrine) is secreted by the inner part of the adrenal gland (the adrenal medulla). It is known as the “emergency hormone” because it prepares the body for sudden “fight-or-flight” responses during times of stress or danger.
