How much do you know about your heart? Thanks to the good folks at WebMD, we are happy to ask some important questions to familiarize you and might even amaze you about how your heart works. Before you peek below to see the answer, give the questions some thought, and test yourself.
Where in your chest is your heart?
A. Center. You likely put your hand on the left side of your heart when you think of your ticker. Your heart is in the center, though, between your lungs. The bottom of your heart is tipped to the left, which is why you feel it beating a little more on your left side.
How many gallons of blood does your heart pump each day?
A. Your heart is a strong muscle that pumps blood to all the organs of your body – 2000 gallons worth each day. During an average lifetime the heart pumps 1 million barrels of blood.
How many times does a heart beat in a lifetime?
A. Each day your heart beats an impressive 100,000 times. That adds up to more than 2.5 billion heartbeats per year.
Your heart can live outside your body?
A. True. Even if all the nerves to your heart were cut, it would keep beating if separated from your body. That’s because your heart has its own electrical system. It just needs oxygen to keep beating.
The bigger your heart, the better?
A. False. A heart that’s bigger than it should be is called an enlarged heart. It’s weak and it holds fluid, causing it to beat irregularly making the lungs get congested.
Which animal’s heart is most like a human’s?
A. Ape. Apes; and monkeys’ hearts are most like humans, similar in how they look and work. But many scientists studying the use of animals as organ donors think the pig might be the most promising. Lots of research is being done.
Be careful of airport security machines if you have a pacemaker?
A. Metal detectors likely won’t cause problems for people with pacemakers. But the TSA asks that people with a pacemaker, defibrillator, or other internal medical device not go through the metal detector. Instead, ask for a pat-down or go through the imaging-technology scan.
The American Heart Association suggests avoiding machines with powerful magnets, like MRIs. Some MP3-player headphones shouldn’t be kept near a pacemaker either.
