Introduction

Our body is very special and helps us do many things every day. It has many parts like hands, legs, eyes, and ears. All these parts work together so we can play, eat, walk, and learn. In this chapter, we will learn about the different parts of our body, what they do, and how they help us. We will also see how we grow from a baby to a big person, just like plants and animals grow!

How Our Body Parts Help Us

Each art of our bod helps us in different ways:

• Legs help us to walk, kick a ball, climb, run, hop, jog, dance, and skip.
• Hands help us to eat food, hold things, write, and lift objects.
• We use our arms, shoulders, and hands together to push, pull, and throw things.
• We use our shoulders and back to carry things like a bag.
• Our back helps us to stand straight, bend forward, and bend backward.
• Our knees help us to bend down, squat, and kneel.
• Our neck helps us to turn our head from side to side.
• Eyes, nose, ears, skin, and tongue are called sense organs.
• Yoga helps to keep our body parts strong and flexible.

How Our Sense Organs Help Us

Sense organs help us know about things around us:

• Nose helps us to smell things. Smells can be good or bad.
• Eyes help us to see. We can see the size, shape, and color of things around us.
• Ears help us to hear different sounds. Sounds can be loud or soft.
• Tongue helps us to taste things. We can taste sweet, sour, bitter, and salty things.
• Skin helps us to feel things. We can feel hard, soft, hot, cold, smooth, and rough surfaces.

Fun Fact

Skin is the largest sense organ in our body.

Growing Older

• We are born as babies.
• From a baby, we grow to be a girl or a boy.
• Then we grow to be a young woman or man.
• After many years, we start growing old.
• As we grow older, we become weak, and our looks change.
