The cellular and acellular components that together form a individual multicellular organism.
Animals are not the only organisms that have bodies. That is, multicellular fungi have bodies as so too do plants and multicellular algae.
Even less obvious is whether unicellular or simply colonial organisms possess bodies with perhaps a distinction between true multicellularity and mere colonial living being whether or not the entity can reasonably be described as having a body.
The science of physiology, at least as applied to multicellular organisms, is the study of the functioning of bodies.
