What is blood?

Blood is like a special liquid that travels inside your body, helping you grow and stay healthy.

Think of blood as a superhero team working together. Some parts help carry food to all the parts of your body, just like how a lunch truck brings snacks to every classroom in school. Other parts help take away the waste from your body, like how you put trash in a bin and then take it out.

Blood is made up of different ingredients, kind of like how cookies are made with flour, sugar, and chocolate chips. One part is called red blood cells, they look red because they carry something called hemoglobin, which helps bring oxygen to your muscles so you can run and play.

Another part is plasma, the clear liquid that holds everything together, like how water holds ice cubes in a glass. And there are tiny helpers called platelets, which help stop bleeding when you get a scrape, just like how a bandage helps a wound heal.

Blood keeps your body moving, growing, and feeling good!
