What are subcutaneous canals?

Subcutaneous canals are like tiny tunnels under your skin that help move things around inside your body.

Imagine you have a toy box full of blocks, and you want to move them from one side of the room to another. If there were little tunnels connecting the sides of the room, you could just roll the blocks through them instead of carrying them all the way. That’s kind of what subcutaneous canals do, they help move important stuff like fat or fluid around under your skin.

Think of your body as a city with lots of roads. The subcutaneous canals are like small streets just below the surface, helping things travel from one place to another without going all the way through the whole city.

These tiny tunnels are especially important when you're growing or changing shape, they help your skin stay smooth and flexible, like how a sweater stretches when you wear it.
