what is your heart?

Your entire system gets blood pumps from your heart. your heart  is the most important organ in your body. did you know that your heart beats more than 10000 times a day. your heart is the leader of your organs and keeps the blood for your body. your heart carries about 2.5000 a day.

Your veins carries oxygenated blood and your arteries carries deoxygenated blood. Your heart can move on its own were as all of your other organs need help from your heart. the blood cells starts in the right atrium and then travel through the left atrium. the reason that the circulatory system is called that is because the system moves in a circle.


circulatory system

The heart is a vital organ that pumps blood around the body. The heart is a curtail part of your body because it help us humans survive. this is because without the heart you would not have any blood and you will stop breathing. The heart carry the oxygen around the body which, helps us breath. Then the lungs will relies the carbon dioxide. The  average amount of  heartbeats is about 100,000 times which means in your life your heartbeats over 2.5 million times. Your heart is the same size as your fist clench.

The human circulatory system is made up of the heart, blood vessels and the lung. Without this we would die as soon as we were born. Every part of our body is important and we need. blood is red and veins. The heart goes first right atrium, then the tricuspid valve (like a door way that only open one way). (otherwise the oxygen and carbon dioxide go together and then you might die) then the right ventricle finally up the pulmonary  valve. The returning blood cells the first left atrium then through then through the left ventricle the to the aortic valve. When you breath in oxygen then it goes to your lungs and then you breath carbon doxiade out.

Have you ever wondered what your heart is?                                                                                             your heart is a vital organ to your body and it is essential to life because it keeps your blood pumping around your body. If you didn’t have a heart you would honestly die. Your heart is the most important organ in your body and it beats around 10,000 times a day and around 2.4 billion times in a lifetime. Your heart transports about 2,000 gallons a day.

But the real question is how does your heart work?                                                                                    It all starts when your red blood cells travel into the right atrium and travels through a passage called a valve to the right Ventricle , from there it travels in a vein ( A vein is for non oxygenated blood) to the lungs, the blood cells bounce of the sides of the vein and all of the oxygen particles stick to the blood cells then it travels to the lungs to collect some more oxygen and then it heads down a archery (an archery is for oxygenated blood) and back to the heart. When the red blood cell reaches the heart again it travels into the  left atrium and again through a valve to the left ventricle from there it travels down an archery to give another part of the body the oxygen it needs for example the foot. When your red blood cell reaches the foot the oxygen floats off and carbon dioxide sticks to the red blood cell and then the cell travels up an archery and then the cycle continues.

The Circulatory System – Big Write

The human heart is a vital organ in the body which pumps blood. It carries blood and oxygen to other parts of the body. It beats around 100,000 times a day and translates about 2,000 gallons of blood everyday. It sits in the chest just a little bit to the left, in front of the left lung. Your heart is about the size of a clenched fist. It also pumps blood every time it beats. If you didn’t have a heart then you would die.

First, the blood cell goes through the right atrium. Then, it goes through the tricuspid valve and the right ventricle. The blood vessel goes through the arteries deoxygenated, then the heart sends the oxygenated blood through the veins. After that, it comes into the left atrium, left ventricle,  aortic valve and to where the oxygen is needed. Then, the cycle restarts.

Here are some facts: Did you know that every second, 8 million blood cells die, and the same number are born? The heart beats around 3 billion times in a persons life.

How does the heart work and what is it?

The heart, is a vital  organ inside of you. Your body, depends on it all the time. without the heart we would not be here today. The heart is about the size of you fist  clenched. Also the heart beats 100,000 and the heart beats 2.5 billion times a lifetime. The heart is located in your chest on the left of you sternum. When you grow your heart grows because when you grow your heart needs to work twice as you grow. Your veins  grow as you grow up  so you heart needs to grow as you do as your veins develop. Your blood  takes  nutrients around your body.

First, your blood contains blood cells that go to the lungs and take oxygen from them to give it to the heart your blood must have oxygen .The oxygen stick to the blood cells and the blood cells then take it back to the heart. When blood cells have got all the oxygen they then take it to the left atrium and than to the right atrium.  The blood cells are bumped all around the body this is why you can hear and feel your heart bet. If there was no oxygen (which is on the lungs)the system would not work probably..  The heart never stops and always  beats  every day. This whole process happens in the time it takes you to blink.

Some extra facts 

The heart is one of the most hard working thing inside of your body. Your heart does this over 100,000 times a day.
