Your
heart is a very important organ. It is working very
hard for you day and night. If your heart
doesn¡¯t work well, you will suffer from many health problems. But how
much do you know about your heart? This week, let¡¯s learn some amazing
facts about your heart.
The heart is made up of four chambers: the left atrium, right atrium, left
ventricle, and right ventricle.
Your heart is about the size of a fist. Most people think that
the heart is on the left side of the chest. However, in reality, the heart is
in the middle of the chest, between
the two lungs.
The heart is a pump that pushes blood throughout the body. The
heart moves blood by expanding and contracting. The heart beats about 100,000 times
each day to push blood. The
normal pulse for humans is
70 heartbeats per minute.
In a lifetime, the heart pumps
about one million barrels of blood. In fact,
your heart has to push blood through about 96,560 kilometers of blood vessels.
That is long enough to circle the Earth two and
a half times! During your lifetime, your heart will beat about 2.5
billion times.
The right lung of a human is larger than the left one. This is because
of the space and placement of the heart. A
male heart weighs about 280 to 340 grams.
A woman¡¯s heart weighs about 230 to 280 grams. Women¡¯s hearts beat
faster than men¡¯s.
Your heart
is very important, and you need to treat it with care. About 2,700 people
in the world die of heart disease every day.
Regular exercise and healthy
foods can help your heart do its job well.
Eating Omega-3 fatty acids, almonds,
and walnuts is good for your
heart. These foods are easy to enjoy. Just put some almonds and walnuts
in your yogurt, salad, or cereal. Blueberries, salmon, oatmeal, and soy protein are also heart-healthy foods. So,
don¡¯t forget to enjoy these foods
every day for your hard-working heart! |
