When something swells, it means it gets bigger or puffier. Imagine a balloon. When you blow air into it, it gets bigger and bigger. That’s like swelling! Sometimes, when you get a boo-boo or a bump, your skin can swell up and look like a little hill. It’s your body’s way of saying, ‘Hey, I need to fix this!’
Think of a sponge in water. When it’s dry, it’s small and light. But when it soaks up water, it grows and feels heavier. That’s swelling too! Your body might swell up like a sponge when it’s trying to heal.
Or, picture a marshmallow in the microwave. As it heats up, it puffs up and gets bigger. Swelling is like that marshmallow getting warm and expanding.
So, swelling is just something getting bigger, like a balloon, a sponge, or a marshmallow. It’s a way to know that something is changing or healing.
