Answer:
Because the functions of our organs, tissues and systems, are dependent on their unique morphology or structure.
Explanation:
For example, a tissue that functions in an area that smooth and easy diffusion of materials is important cannot have a small surface area to volume ratio because with that kind of structure it cannot function in that environment and carry out the needed functions. Also, If the structure of a bone is altered it can no longer function as a tool for support and movement of the body or the particular area in which the structure was altered because the structure is needed for it's function.
