ClassX Video Lessons The Human Heart for Kids | Educational video to learn all about how the heart works
Put your hand on the left side of your chest. Can you feel something thumping? That’s your heart beating! Let’s discover some cool facts about the heart and how it works.
Your heart is super important because it helps keep you alive. It’s about the size of your fist and sits on the left side of your chest, protected by your rib cage. The heart is part of the circulatory system, which moves blood around your body. This system delivers oxygen and nutrients to every part of you.
The heart is a special muscle that beats all by itself. You don’t have to think about it; it just keeps going! Every day, your heart beats about 115,000 times. That’s a lot! The blood in your body travels 12,000 miles each day, which is like driving across the United States four times!
When you’re playing or running, your heart beats faster because your body needs more oxygen. When you’re resting, it slows down.
Your heart has four main parts: the left and right ventricles at the bottom, and the left and right atriums at the top. Blood moves from the atriums to the ventricles through tiny gates called valves. These gates make sure the blood flows the right way.
Let’s follow the blood’s journey! Blood comes from the lungs full of oxygen and enters the left side of the heart. Then, it’s pumped all over your body through blood vessels, which are like little train tracks. After delivering oxygen, the blood returns to the right side of the heart and goes back to the lungs to get more oxygen.
As blood travels, it also carries food, minerals, and vitamins to help your body grow and stay healthy. Anything your body doesn’t need is sent out as waste.
It takes just about one minute for blood to travel all around your body!
Your heart is amazing, and you can help keep it strong! Here are some tips:
Your heart is a fantastic organ that pumps blood and carries oxygen and nutrients to all your cells. You can make it stronger by staying active and healthy. Next time you go somewhere, see if you can walk or ride your bike, and remember to drink lots of water!

**The Human Heart for Kids**
Take a moment and put your hand on the left center of your chest. Do you feel something? It is your beating heart! Let’s learn some amazing facts about the heart and how it works.
The heart is one of the most important organs in the body and is essential for survival. About the size of a fist, it is located on the left side of the body behind the breastbone in an area called the sternum. The heart is also protected by the rib cage.
The heart is part of the circulatory system, which circulates or moves blood to and from the heart. This system carries vital oxygen and nutrients to every cell in the human body. The two main parts of the circulatory system are blood vessels, which include arteries, veins, and capillaries, and the heart.
Unlike other muscles in the body, the heart beats automatically. This means you don’t have to think about making your heart beat; it just does it for you. This is because your heart is controlled by the autonomic nervous system. In fact, in 24 hours, your heart averages around 115,000 beats per day. During that same time, the six quarts of blood in your body travels 12,000 miles—that’s the equivalent of driving across the United States from coast to coast four times!
The average heartbeat of a child is around 90 beats per minute and will be faster or slower based on what you’re doing. When you are moving your body, your heart beats faster because your body needs more oxygen, and when you’re resting, your heart beats more slowly.
Let’s look more closely at how the heart functions. There are four main parts to the human heart: the left and right ventricles are at the bottom, and the left and right atriums are at the top. Blood is pushed from the atriums into the ventricles on each side of the heart as small valves open and shut during every heartbeat. Think of them as little gates that open and close each time the heart beats. These gates make sure the blood flows in the right direction.
Let’s follow the path blood takes through the heart. These drops of blood have just come from the lungs and are now oxygenated, meaning they are full of oxygen and ready to go. They come from the lungs and are pumped through the left side of the heart, then spread throughout the entire body by blood vessels. Think of blood vessels like little train tracks taking blood where it needs to go.
Once the blood has traveled throughout the body, it returns to the right side of the heart. Just like before, it goes through the gate and then these drops of blood are pumped back to the lungs to gather more oxygen and repeat the process.
As blood moves through your body via the circulatory system, it not only carries the oxygen your body needs but also other important things like food, minerals, and vitamins. These help your body move, grow, and make repairs. It also helps you think. The stuff in your blood that your body does not need is sent out as waste through your lungs, kidneys, and liver.
Here’s a fun fact: the trip for a drop of blood to travel throughout your body takes only about one minute! Since the heart is a necessary part of the body, it is important to care for it and keep it healthy. Here are some ideas to keep your heart healthy and working for a long time:
1. **Exercise**: The heart is a muscle, and just like other muscles in your body, exercise can help it become stronger.
2. **Eat Fruits and Vegetables**: Food affects your heart too. Eating lots of fruits and vegetables helps keep your arteries clear for better blood flow.
3. **Drink Plenty of Water**: Keeping yourself hydrated is essential for keeping your heart pumping blood. About 75% of your brain and heart are made up of water, and your blood is about 83% water, so you need to drink water to keep your heart healthy.
4. **Remember to Move**: Sometimes when we are doing homework or watching a screen, we might forget to get up and move around. It is important to take breaks and move your body; it’s good for your heart and your mind.
The human heart is a pretty cool organ. As part of the circulatory system, it pumps blood through your body and carries oxygen, nutrients, and minerals to all of your cells. The coolest part is that you can help make your heart stronger! So the next time you go to a friend’s house or to school, see if it’s safe to walk or ride your bike instead of driving, and make sure you drink plenty of water.
