What are tissues?

Tissues are groups of cells that work together to do a job in your body.

Imagine you're building a LEGO castle. Each brick is like a cell, and when you put several bricks together, they make a wall, just like how cells come together to form a tissue. In your body, different tissues have different jobs. For example, the tissue on your skin helps protect you, just like a wall protects a castle.

Some tissues are strong and help you move, like the ones in your muscles. When you run or jump, these tissues stretch and contract, kind of like elastic bands that help your legs swing forward.

Other tissues are soft and squishy, like the ones inside your belly. They help hold things like food and water, just like a backpack holds your lunch.

Your body has four main types of tissues: muscle, nervous, connective, and epithelial. Each one plays a special role, but they all work together, like friends on a team, to help you grow, move, think, and feel.

Tissues are the building blocks of your body, just like bricks are the building blocks of a castle!
