Sound smart at your next dinner party with these heart-warming facts

1. It’s your body’s electric motor.

Cells in your body can’t ‘fire’ unless they are stimulated. The only exception is the sinoatrial node (SA node), a bundle of self-starting neurons. The SA node fires and the electrical charge produced is what makes your heart pump, circulating your blood.

2. Chest pains aren’t the only sign of a heart attack.

Although tightness or discomfort in the chest is a common symptom, others include nausea, sweating, shortness of breath or feeling lightheaded. Having pain in your back, arms, neck, or stomach are also likely symptoms.

The top 2 chambers are known as atrium (plural is atria) and the bottom 2 chambers are called ventricles. The right side collects low-oxygen blood and send it to the lungs, while the left side accepts oxygen-rich blood from the lungs and distributes it out to the body.

4. Men and women’s hearts are different.

The average weight for a man’s heart is 10 ounces, while a woman’s is 8 ounces. However, women’s hearts beat slightly faster at 78 beats per minute, while the average heart rate of a man is 70 beats per minute.

5. It isn’t found on the left side of your chest.

Your heart is situated closer to the center of your chest, behind the sternum or solid center of your rib-cage. It may feel like the heart beats from the left side of your chest because that is the side that pushes blood out and into the body.

6. Your heart is not red.

Despite cartoon renditions, your heart is a muscle that is darker and almost brown compared to the traditionally imagined crimson red.
