The Human Body

Our bodies are made up of many parts, and they all work together to help us move, play, eat, breathe, and grow!

Skeleton - Your skeleton is made of bones. It gives your body shape, helps you stand up tall, and keeps you strong. Bones also protect the important parts inside you, like your heart and brain. Your muscles are attached to your bones. When your muscles move, they pull on your bones and help you run, jump, and dance!

The bone in your head is called the skull. It’s like a hard helmet that keeps your brain safe.

Brain - Your brain is the boss of your body. It tells everything what to do! It helps you think, feel, move, speak, and remember. Your brain also controls things you don’t even think about, like breathing and blinking.

Heart - Your heart is a very important organ. It works like a pump. It sends blood all around your body. The blood carries oxygen and nutrients to all the parts that need them.

Lungs - You have two lungs inside your chest. They help you breathe. This organ takes oxygen from the air and transfers this to your blood. It then gets takes carbon dioxide from your blood and you breathe this out.

Stomach - Your stomach helps you digest food. That means it breaks the food into tiny bits your body can use for energy, so you can grow strong and stay healthy!

Growing up

Everyone starts life as a tiny baby. Babies can’t walk or talk yet, but as they get older, they grow bigger and learn new things.

As you grow, your bones get longer, your muscles get stronger, and your brain learns more and more every day.

One day, you'll be a grown-up too! So eat healthy food, get plenty of sleep, and keep moving to help your body grow.

Our bodies are truly amazing! We use them every day to learn about the world around us. One the ways we do this is with our five senses.

Senses help use see, hear, smell, taste, and touch. They are like superpowers that help our brain understand what's going on.

We use different parts of our body for each sense.

Eyes - We use our eyes to see. This sense is called sight.
Ears - We use our ears to hear sounds. This sense is called hearing.
Nose - We use our nose to smell. This sense is called smell.
Tongue - We use our tongue and mouth to taste. This sense is called taste.
Skin and hands - We use our skin, especially our hands, to to feel things. This sense is called touch.

Each sense is important and helps keep us safe and happy. Imagine if one of your senses didn’t work. What would that feel like?

Try this fun activity:
Ask someone to blindfold you (cover your eyes). Then try to walk to the door. But make sure a grown-up or friend helps you, so you don’t bump into anything.
Or try watching your favourite TV show with the sound turned off. Is it still fun? Or is it harder to understand what’s happening?

Our senses work together to help us explore, play, and learn. That’s why it’s important to take care of them!

To stay strong and healthy, we need to eat the right amount of different kinds of food. This is called a balanced diet.

There are five main food groups:

Fruit and vegetables - full of vitamins to keep you healthy
Carbohydrates - like bread, rice and pasta to give you energy
Proteins - like meat, fish, eggs and beans to help you grow
Dairy - like milk, cheese and yogurt to keep your bones strong
Sugars & fats - tasty, but we only need a little bit.

Can you name one food from each group that you like to eat?

Why do I need to exercise?

Exercising keeps your heart, lungs and muscles strong and healthy. We need to exercise every day to keep your body in tip top condition. Have you ever ran about so much that your can feel you heart beating quickly and hard afterwards? That's a good thing. It means that your are making your heart stronger by working hard. It is also working your lungs too.

Exercise can make us feel better as well. Exercising can make us feel happy and more positive and give us a lot more energy. It helps us to concentrate and it can also help us sleep well at night too.

How much exercise do I need?

Children between 5 and 8 years old should do one hour of exercise a day if they can. You can tell if you have worked hard enough if you start to feel sweaty and your heart is beating fast.

Washing your hands

Washing your hands stops germs spreading. We all put our hands near our nose and mouth during the day. If you have been to the toilet and have not washed your hands you will certainly spread those germs to your face and you are likely to become sick. Knowing how to wash your hands properly can reduce the amount of times you get sick.

Use a tissue when you have a cold to stop spreading your germs to other people. Hold the tissue over your mouth when you cough or sneeze then throw the tissue in the bin. Do not leave tissues lying around when you have used them to wipe your nose. Always put dirty tissues in the bin and wash your hands afterwards.

Looking after your teeth

Brushing your teeth twice a day helps remove any sugar that may build up around your teeth and gums. If we let this sugar build up it could damage our teeth.

How well do you brush your teeth?

Ask in a pharmacy for a special tablet that turns all the plaque in your mouth coloured and see if you can brush your teeth clean. Notice how long it takes, you should aim to brush your teeth for 2 minutes, twice a day. Find a timer and time yourself brushing.

NOTE: Please follow the instructions on the packet carefully.

Take a look at your teeth in a mirror. Can you see that they are not all the same? How many teeth do you have? Now count how many teeth an adult has. Do you have more or less than them?
