We ♥ Hearts!

aorta-151145_1280

The heart is one of the most important organs in the human body. Your heart, which is slightly larger than a fist, helps keep your body functioning by pumping blood through blood vessels throughout your body. Since your heart is very important it safely resides in your chest and is protected by your rib cage. Inside your heart are four valves that help to ensure blood only goes one way. When the heart contracts it causes the blood to pump out into the body which creates a heartbeat. The average heart beats about 100,000 times a day and pumps roughly 2160 gallons of blood a day.

Crazy Little Thing Called Love

heart-762564_1280

When Cupid brings out his arrows on Valentine’s Day it isn’t just our hearts that begin to change when love is in the air. Falling in love effects both your brain and your heart which can in turn effect other parts of your body as well. It turns out that love truly is a chemical reaction that takes place in our bodies. The four compounds; dopamine, norepinephrine, oxytocin, and serotonin (always present in our brain) increases and interact causing what we refer to as ‘love’.  Being in ‘love’ also causes your adrenaline and norepinephrine levels to increase which causes the butterfly feeling we get in our stomachs. All of these chemicals are what causes our cheeks to flush, our palms to sweat, and our hearts to race. So this February, don’t worry about love being in the air… it’s actually in your head!
