Adrenaline (also known as epinephrine) is a hormone secreted by the adrenal medulla (part of adrenal glands) and is often referred to as the "emergency hormone"
or "fight-or-flight hormone". It prepares the body to face sudden stress or danger by initiating several physiological changes, including:
Heart beats faster → Adrenaline increases heart rate to supply more oxygen to muscles.
Breathing rate increases → This enhances oxygen intake for immediate use.
Adrenaline is secreted by adrenal glands located above the kidneys.
It prepares the body for emergency situations like fear, anger, or stress.
It causes pupil dilation, increased blood flow to muscles, and glucose release from liver.
