Why does our heart beats faster when we're inlove?

(CNN) -- Poets, novelists and songwriters have described it in countless turns of phrase, but at the level of biology, love is all about chemicals.
Although the physiology of romantic love has not been extensively studied, scientists can trace the symptoms of deep attraction to their logical sources.
"Part of the whole attraction process is strongly linked to physiological arousal as a whole," said Timothy Loving (his real name), assistant professor of human ecology at the University of Texas, Austin. "Typically, that's going to start with things like increased heart rate, sweatiness and so on,"
When you catch sight of your beloved and your heart starts racing, that's because of an adrenaline rush, said Dr. Reginald Ho, a cardiac electrophysiologist and associate professor of medicine at Thomas Jefferson University Hospital in Philadelphia, Pennsylvania.
Here's how it works: The brain sends signals to the adrenal gland, which secretes hormones such as adrenaline, epinephrine and norepinephrine. They flow through the blood and cause the heart to beat faster and stronger, Ho said.
The response is somewhat similar to a fast heartbeat while running on a treadmill, although exercise has other benefits, he said.
For people with serious heart problems, love could actually be dangerous, Ho said.
That's because when the heart rate goes up, the heart uses more oxygen, which can be risky for an older person with blood vessel blockages or who has had a prior heart attack. But good medicines such as beta blockers help curb the adrenaline response, Ho said.
It is also likely that norepinephrine, a stress hormone that governs attention and
responding actions, makes you feel weak in the knees, said Helen Fisher, professor at Rutgers University and author of the book "Why Him? Why Her? Finding Real Love by Understanding Your Personality Type."
Fisher's research team did brain imaging of people who said they were "madly in love" and found activity in the area of the brain that produces the neurotransmitter dopamine. Dopamine and norepinephrine are closely related.
"What dopamine does is it gives you that focused attention, the craving, the euphoria, the energy and the motivation, in this case the motivation to win life's greatest prize," she said.
This norepinephrine response has never been precisely studied in relation to romantic love, but the system seems to be more activated in people in love, she said.
Also likely involved is the serotonin system,she said. Some data from an Italian study indicate that a drop in serotonin levels is associated with obsessive thinking.
The stress hormone cortisol has also been shown to have implications for love, Loving said. His lab showed study participants who had recently fallen in love a picture of a romantic partner or friend, and had them describe or "relive" the moment of falling in love or wanting to be friends, respectively. Those who recalled falling in love showed an increase in stress hormones such as cortisol even 30 minutes after they were asked to think about it.
Generally, there are three brain systems involved in romantic love: s*x drive, love and attachment, Fisher said.
