      Cells are the building blocs of the tissues. For example, the skin is a tissue composed by different types of cells (all of them have complicated names, like keratinocytes, melanocytes, Langerhans cells…). Each cell type specializes in a particular function. For example, melanocytes generate melanin, which gives the colour to the skin and protects us from the sun. All the cells cooperate to make the tissue work.

      Tissues are made up of cells, that are all talking to each other and trying to work together to achieve a goal. It is usual that several different cell types are needed to make up a tissue. Each type of cell within the tissue has its own role and job to do – diseases can happen when one type of cells isn’t doing its job properly.
