The heart plays an integral function in your body. It pumps blood to all the parts of your body, facilitated by the arteries and veins. The heart and blood vessels play an important role in keeping the human body alive. The heart is a muscular organ like other muscles but it is a little special. Without the function of the heart, a body cannot work in any way.
The Heart
The heart performs its function like a pump. It has a right and left side. The right side pumps the blood to the lungs after taking it from the body. The left side performs the opposite function of taking blood from the lungs and giving it to all the other parts of the body. Let us learn more about the heart system in the human body.
Parts of the Heart
Chambers, atrium, ventricles and aorta are the parts of a heart. Chambers are the four blood-filled parts of a heart which play an important role in its functioning. The top chambers are called atria and the bottom ones are called ventricles. Atria are the blood-filled chambers which receive blood from the body and lungs. It is divided into two parts called right atrium and left atrium.
Parts of the Heart
Ventricles are the bottom chambers which give blood to the lungs and body. They are also divided into two parts. The right ventricle and left ventricle are the two parts of the heart. Aorta is the main artery in your heart. All these parts working together leads to the pumping of the heart. The heart pumps when it receives blood and sends the blood to other parts.
Circulatory System for Kids
The circulatory system is connected with the heart and blood vessels in the body. As the name suggests, it does the circulation of blood in the heart. It performs a very important function in the body. It is made up of vessels which carry blood to the heart and from the heart to the body. Arteries and veins together undertake this task. Veins take the blood to the heart and arteries carry it away from the heart.
It also carries other things like oxygen, nutrients and cells with it. It works as a protector as well by keeping waste products like carbon dioxide. Pulmonary Circulation and Systemic Circulation are the two parts of the circulatory system. The former is a loop kind of organ connected from the heart to the lungs and the latter carries blood from and to the heart to other parts.

FAQs on Heart Facts for Kids - The Most Important Organ in the Body
1. What is the main job of the heart in our body?
The main job of the heart is to act like a powerful pump. It continuously pumps blood to all parts of your body. This blood carries essential things like oxygen and nutrients that your body needs to live and stay active, and it also carries away waste products like carbon dioxide.
2. Where is the heart located and how big is it?
Your heart is located in the chest, slightly to the left side, and it is safely protected by your rib cage. For most kids and adults, the heart is about the size of their own fist.
3. Is the heart just a muscle?
Yes, the heart is a very special and strong type of muscle called the cardiac muscle. Unlike the muscles in your arms or legs, the cardiac muscle works automatically all day and night without ever stopping or getting tired, pumping blood to keep you alive.
4. What are the main parts of the heart?
The heart has four main sections called chambers. The two top chambers are called atria (atrium for one), and the two bottom chambers are called ventricles. They work together as two separate pumps for the right and left sides of the heart to move blood efficiently.
5. What are some amazing facts about the human heart?
The heart is a fascinating organ! Here are a few amazing facts:
- Your heart beats about 115,000 times each day.
- It pumps around 2,000 gallons (or 7,500 litres) of blood every single day.
- The sound of your heartbeat is made by the heart's valves opening and closing.
- The heart has its own electrical system that tells it when to beat.
6. Why is the heart often called the body's engine?
The heart is called the body's engine because, just like an engine provides power to a car, the heart provides the power that keeps your body running. By pumping blood, it delivers the 'fuel' (oxygen and nutrients) that every single cell, tissue, and organ in your body needs to function.
7. How do the heart and lungs work together as a team?
The heart and lungs are best friends and work as a team. The right side of the heart pumps blood that has low oxygen to the lungs. In the lungs, the blood picks up fresh oxygen. Then, this oxygen-rich blood travels back to the left side of the heart, which pumps it out to the rest of the body.
8. What happens to our heartbeat when we run or play?
When you run, jump, or play, your muscles work harder and need more oxygen. To supply this extra oxygen, your brain tells your heart to beat faster. This increased heart rate pumps blood more quickly, ensuring your muscles get the energy they need to keep you moving.
9. What are the best ways for kids to keep their hearts strong and healthy?
Keeping your heart healthy is important for a long and active life. The best ways to do this are:
- Eat a nutritious diet: Include plenty of fruits, vegetables, and whole grains.
