Paragraph on ‘How Does Our Heartbeat?’ in 200 Words
The heart is a very important part of our body. It is a muscle located in our chest, and its job is to pump blood. This blood carries oxygen and nutrients to every part of our body, giving us the energy to play, think, and grow. The heart has strong muscles that squeeze and relax, creating a beat. Each beat sends blood out through tubes called arteries. It also brings blood back to clean it and get more oxygen. The heart makes a sound like a “lub-dub” because the small valves inside it open and close as blood moves through.
Your heart beats all the time, even when you are sleeping or resting. You can feel it working if you touch your wrist or neck to find your pulse. The harder you exercise, the faster your heart beats to send more oxygen to your muscles. To keep your heart healthy, eat good food, stay active, and get enough sleep. The heart works like a loyal pump, keeping you strong and alive every single day.
Paragraph on ‘How Does Our Heartbeat?’ in 300 Words
Our heart is an amazing part of our body! It is a muscle about the size of your fist, and it sits in your chest, slightly to the left. The heart’s job is to pump blood to every part of the body. Blood carries oxygen and nutrients that our body needs to stay healthy. Without the heart, the blood cannot move, and our body cannot work.
The heart beats because its muscles squeeze and relax, just like a pump. This happens thousands of times every day. The heart has four parts, or chambers, that help blood flow in the right direction. Inside, there are tiny doors called valves that open and close to keep blood moving. The opening and closing make the sound “lub-dub,” which we call a heartbeat.
The heart works harder when we run or play because our muscles need more oxygen. When we rest, it slows down but never stops. You can feel your heartbeat by checking your pulse on your wrist or neck. This is the blood moving through your veins.
To keep your heart healthy, eat plenty of fruits and vegetables, exercise often, and drink water. Your heart is like a hard-working engine, keeping you alive and full of energy every day!
