- Blood cells have a role in providing us immunity (for example white blood cells) therefore, make us better able to protect ourselves from danger of diseases.
- Muscle cells help us in moving our organs as well as allowing the whole movement from one place to another.
Thus we see that different types of cells have special functions and all these different cells coordinate with each other to make an organized and functioning body of a living organism.
