Introduction
We see and hear about our heart, a non-stop worker of our body somewhere. Previously peoples thought that their emotions came from their hearts, maybe because the heart beats faster when a person is scared or excited. Now we came to know that the emotions come from the, and that brain tells the heart what to do. Here Let us know the A-Z things about that Non-stop worker, the Heart elaborately.
Location
Your heart is located a little to the left of the middle of your chest, and it’s about the size of your fist. No muscle is as special as your heart muscle, because of what it does. The Heart pumps the blood around your body with oxygen and nutrients which your body needs. It also carries the waste that your body has get rid of. The right side of your heart receives the blood from the body and pumps it to the Lungs. The left side receives blood from lungs and pumps it out to the body.
An Amazing Job
How does the heart beat? Before each beat, it fills with blood. Then its muscle contracts to squirt the blood along. When it contracts, it squeezes – try squeezing your hand into a fist. That’s sort of like what your heart does this all 24X365 hours. Everyday, an adult heart pumps 2000 gallons (7500 ltrs) of blood by filling and contracting and sending the blood around and around again. What a amazing work it is!

Parts of the Heart and Controls
(refer above figure)
The Heart is made up of four different blood-filled areas named as chambers. And there are two chambers on each side of the Heart at Top and Bottom. The Two Top chambers and other two bottom chambers are called as “auricles” and “ventricles” respectively.
The auricles are the chambers that fill with the blood returning to the heart from the body and lungs. The Ventricles job is to squirt out the blood to the body and lungs. Running down the middle of the Heart is a thick wall of muscle called the “septum”, a separator muscle of right and left heart.
The auricles and ventricles work as a team- the auricle fill with blood, then dump it into the ventricles. While Ventricles pump the blood out the heart, the auricles refill and get ready for the next contraction. This pumping system is controlled by four valves. Two of them are called as “mitral” and “tricuspid” valves, and they let blood flow from the auricles to ventricles. The other two are called the “aortic” and “pulmonary” valves, and they are in change of controlling the flow as the blood leaves the heart. These valves all work to keep the blood flowing forward. They open up to let the blood move ahead, then they close quickly to keep the blood from flowing backward.
Circulation – The Blood Movement
Do you know how much time the blood takes for one Circulation? Only 20 seconds. In this every 20 second the blood pumped to each and every cell in the body. Your Body needs this steady supply of blood to keep it working right.It also needs the blood to get rid of the waste that would make your body sick if it stuck around.
The left side of your Heart sends blood to the body, which contains lot of oxygen, the one of the things that your cells need to stay alive. The body takes the oxygen out of the blood and uses it in your body cells. Thus the blood has done its job by delivering the oxygen to the cells, and now it’s time to pick up the Trash – the Carbon-dioxide and other wastes.
Each time of the blood circulation, about 20% of it goes through the where some of the waste is taken out, and then the blood to be carried away. The right side of the heart is ready for the hands off. It takes the blood to the lungs for a little freshening up. The Carbon dioxide leaves the blood by getting breathed out by the lungs, and the oxygen gets into the blood from the air we breathed in. Now the blood has got the oxygen it needs to go back to the left side of the heart and start its cycle overall. You might think that this process takes near about 10 to 15 minutes. No its takes only half a minute.
The above all circulation of blood is done by the blood vessels which was attached to the heart to overall our body.Simply Blood vessels are nothing but the tubes that carry the blood around the body, also named as “veins and arteries”.
The NonStop Music Lub-Dub
When you go for a check up, your doctor listens carefully the Lub-Dub, your heart beat which the healthy heart makes evenly. This sound comes from the valves opening and shutting on the blood inside the heart. The sound “Lub” happens when the blood hits the mitral and tricuspid valves between the artria and ventricles. The next “Dub” happens when the blood hits aortic and pulmonic valves that close up after the blood has been squeezed out of the heart and as the heart relaxes to fill with blood for the next beat. A Healthy heart beats 70 to 100 times per minute, when you are resting.When you run around a lot, your body needs a lot more oxygen filled blood. Hence the heart pumps faster to supply the oxygen filled blood that your body needs.
Keep Your Heart Happy
Most kids are born with a healthy heart and it’s important to keep yours in good shape. Here are some things that you can do to help keep your heart happy:
· Remember that your heart is a muscle. Just like you need to exercise your leg and arm muscles, you need to exercise your heart too. Aerobic exercises like walking, running and swimming, is a great way to keep your heart in shape.
· Eating a variety of healthy foods is great for your heart. Avoiding a lot of high fat foods will help to keep your heart happy too.
· Stay away from smoking! Smoking is bad for every part of your body, and especially your heart. Your heart and blood vessels hate cigarettes because smoking makes their jobs much harder and can damage them.
So now you know that your heart started pumping blood before you were born, and will continue pumping throughout your whole life. So take good care of your heart and it will take extreme care of you!
