Adrenaline molecular structure
What is adrenaline
Epinephrine, also known as epinephrine, is a hormone secreted by a molecule of the adrenal glands.
Adrenaline is very important for maintaining life. Under normal conditions, its presence in the blood is very small. However, in times of excitement (fear, euphoria) or emotional stress, a large amount of adrenaline is secreted to act on certain parts of the body (nerves, muscles, legs, arms) in order to prepare you for physical exertion. (running, jumping and movements that require reflexes quickly).
Adrenaline stimulates the heart (increases heart rate), stimulates vessel constriction, raises blood pressure, releases glucose stored in the liver, relaxes some involuntary muscles while contracting some others.
Medical use of adrenaline
Epinephrine is widely used as a medicine to stimulate the heart in cases of cardiac arrest, to prevent bleeding and to dilate the bronchioles of the lungs when acute asthma attacks occur.
