Tissues are groups of cells that work together to form a specific function.
An example of a tissue is muscle tissue. There are three types of muscle tissue: cardiac, skeletal, and smooth.
These tissues are comprised of cells which work together to form a function - in the case of cardiac muscle tissue, these cells work together to keep the heart pumping blood (to keep it simple).
