Ventilation systems. All multicellular organisms have mechanisms for drawing oxygen-rich air (or water) into their bodies and removing carbon dioxide-rich air (or water).A closer look at insect breathing systems makes it easier to appreciate the functions of the more familiar human ventilation system.entilation systems. All multicellular organisms have mechanisms for drawing oxygen-rich air (or water) into their bodies and removing carbon dioxide-rich air (or water).
Multicellular organisms show emergent properties. For example: cells form tissues, tissues form organs, organs form organ systems and organ systems form multicellular organisms. The idea is that the whole is greater than the composition of its parts. For example your lungs are made of many cells.ulticellular organisms (example: humans) are composed of many cells while unicellular organisms (example: bacteria) are composed of only one cell. Cells are the basic unit of structure in all organisms.
