The only true statement here is that organs are made of tissues. Our bodies and bodies of all animals are made of large number of parts, and each part is made of the smaller parts. When we see a man, we see the whole organism. Organism is consisted of organ systems, organ system is consisted of organs, and organs are consisted of tissues. If you want to see further - the smaller parts of ourselves, you have to use microscope. With its help, you could see a million of cells which make tissue, and these cells are made up of molecules. But, this is not the end: the molecules are made up of even smaller parts, called atoms.
