Hataraku Saibou - does the cell have cells in their bodys'? In the Hataraku Saibou Anime, do the cells have cells in their body? and do those cells have cells?
by cells i mean little people running around the hosts body.
like infinate cells who are running around etc??? #RabbitHole
No, the cells do not have little people running around inside of them. You seem to be accusing the show of making a homunculus argument, a fallacy whereby a concept is explained recursively with itself, but this isn't the case. Importantly, these humanoid cells are not an explanation for what is going on inside the human body. Instead, the cells are an example of personification, whereby animals, ideas, or something else (in this case, cells) are given human characteristics. These humanoid characters are a representation of the thing itself. Of course, in the context of the story these human appearances are important and necessary, but there is no reason to assume the analogy goes so far as for the cells to have little people inside of them.
To illustrate the anatomy of cells, and how they don't have little people inside of them, here are pictures of an erythrocyte and a neutrophil, which is what the two main characters are:
Erythrocyte

Neutrophil

The two humanoid main characters represent the two types of cells above. A cell is the basic unit of life, and is not composed of itself (cells aren't made up of cells). Cells have organelles, cytoplasm, membranes, etc. We shouldn't confuse the personification in this story such that we believe the cell characters are exactly equivalent to human beings and thus end up with a recursive homunculus argument.
Full disclosure: I have only seen the first season of this show. However, you haven't provided any details that would make me think my answer is wrong. Such pertinent details might include, but wouldn't be limited to, a scene in the show where it shows little people inside of one of the characters.
