Organ systems are most complex and fragile starting with the atoms. The most complex organ systems is the organism. In between are the molecules, cell, tissue, organ, and organ system.
cilia; they appear like short hairs under a microscope. Cilia can be found on prokaryotic cells or eukaryotic cells. They can be found on unicellular organisms where they are most likely responsible for movement. In multicellular organisms, they are most often found where the cells need to produce movement for function of the organ system or protection.

The muscle that is responsible for most of a movement is called a prime mover. It may also be called an agonist.
The organ responsible for most of the chemical digestion in the human body is mainly the stomach.
movement is caused by the contraction(shortening) of muscles.

The most complex is organ systems and the least complex is cells. The classical level of complexity is: chemicals, cells, tissues, organs, organ systems, and organism.
