Transcript of The Heart
How they work
There are lots of heart diseases, including heart attacks, congenital disease and heart failure.
The heart works extremely hard to keep you alive by constantly beating, pumping lots of blood, and using heart muscles.
beats about 35 million times a year
Your heart beats about 100,000 time per day
beats more than 2.5 billion times in a lifetime.

What is inside the heart and how it works
when born with malformations of heart's structure.
could be from genes or exposure to too much alcohol in the womb.
could result in holes in the heart or abnormal heart chambers/valves.
9 of every 1000 babies born have a form of heart disease.
Congenital Heart Disease:
when blood flow is suddenly interrupted by complete blockage of an artery.
most known heart disease/injury.
chronic condition happens, when heart is too damaged or weak to pump blood around your body.
your heart still works but organs don't get enough blood and oxygen.
it tends to affect older people more.
Heart beat Rates:
firmly holding and squeezing a tennis ball uses about same amount of force your heart uses to pump blood around the body.
in a day blood travels 19,000 km - 4 times distance across U.S. from coast to coast.
body pumps about 1 million barrels of blood in a lifetime - more than 3 super tankers!
heart muscles work twice as hard as the leg muscles of a human sprinting.
Heart transplants are surgeries that are risky but you have a high chance of survival.
surgeries to remove a person's diseased heart to replace it with a healthy one from a heart donor.
most transplants are done on patients with "end stage" heart failure."End Stage" is when the condition is so sever that all other procedures have failed.
Prevent Heart diseases by eating healthy, being active, and taking steps to prevent diabetes.
Thank you for Watching!

it is when the body's immune system sees the heart as a foreign object and attacks it.
rejection of the donor heart is one of the leading causes of death after a heart transplant.
failure of donor heart,infection, cancer, rejection of the donor heart.
about 87% of people live for at least one year.
about 50% of people live for 10+ years.
people usually live happy lives, are social and active, and go to work.
Too much fat in the blood, high blood pressure, and too much sugar increase your risk of a heart disease.
Eating healthy is important to maintain your blood pressure and amount of fat in your bloodstream.
important because if you're overweight, you have too much fat, which means you'll get higher cholesterol,higher blood pressure, and/or diabetes.
Adults need at least 2 hours and 30 minutes of exercise daily.
Teenagers need 1 hour a day at least 3 times a week to be healthy.
A Heart transplant in process
Your heart pumps more than 3 super tankers worth of blood in a lifetime!
We talked to you about the heart, what's inside, how it works, how it grows,some diseases you can get, how hard your heart works, heart transplants, how to keep your heart healthy, and if it's possible to live without a heart. Now here's a few questions about the heart, lets see what you learned. (there will be prizes)
A baby suffering from Congenital Heart Disease
diabetes is when there is too much sugar in your blood and overtime, if not controlled, it can expose you to heart diseases.
preventing diabetes is easy with 2 main steps; eating healthy, and being active.
Today we are going to talk to you about the heart, what’s inside, how it works, how it grows, some diseases you can get, how hard your heart works to keep you alive, heart transplants, how to keep a healthy heart, and lastly if you can live without a heart.
An organ that pumps blood
One of our most important life sources
Has four chambers (two ventricles and two atria)
Part of the circulatory system and respiratory system
Made up of 4 chambers
Two chambers at the top are called the atria
The two chambers at the bottom are called the ventricle
The muscular wall running down the middle of the heart is called the septum
The atria are responsible for filling up with blood from the body and lungs
The ventricles are responsible for squirting out the blood to the body and lungs
The septum works as a wall to seperate the left and right side of the heart
How the lungs work with the heart
The right side of the heart receives de-oxygenated blood from the body. After passing through the right atrium and right ventrical this blood is pumped to the lungs. Here blood picks up oxygen and looses the gas called carbon dioxide.
How does a heart grow
A heart grows in size
- as you were little you grew bigger yourself, like that your heart grows. An infant heart cannot supply blood for an adult body.
A heart grows in age
- in different ages the heart changes either in a positive way or negative
A heart grows in how it works
- as you get older the heart walls thicken, heart rate slows, the heart doesn't pump as efficiently, and finally the heart as a muscle looses strength.
Can you live without a heart?
Yes you can, last year in March, Craig Lewis, 55 was dying from a heart condition that caused build-ups of abnormal proteins.
Two doctors from the Texas Heart Institute (Dr. Billy Cohn and Dr Bud Frazier) came up with a solution. They would install a "Continuous Flow" device that would allow blood to circulate his body without a pulse. The doctors then took out his real heart and installed this device and within a day he was awake and talking with others.
What are the four chambers called?
The atrias and the ventricles
What are some diseases you can get?
Congenital heart disease
Some ways to keep your heart healthy?
eat healthy, stay active, and take step to prevent diabetes.
In what ways does the heart grow?
It grows in size, age, and how it works.
The heart is very very smart
It works with four main parts
Two atria, and two ventricles
It is extremely incredible
Wonders are at work in the heart
It's as intriguing as art
The heart keeps you alive
And allows you to strive
Although something might go wrong
Maybe because its been strong for to long
But don't worry baby its all good
Because the heart knows whats going on in the hood
Run, jump, skip, and play
Keep it healthy all through the day
Be eating and drinking and dancing and sleeping
Make sure the machine doesn't stop beeping.
