This is a story from inside your body.

On average, humans have approximately 37,000,000,000,000 (37 trillion) cells in their body according to recent theories.

In the world known as a human body, today too, these cells continue to work without rest. Red blood cells carry oxygen, white blood cells fight against bacteria… There, they have their own drama that we do not know about.

If we had to point out a downfall of Hataraku Saibou, it would be the whole ‘lack of a story’ setup that all slice of life & comedy anime tend to have unfortunately. If you can get past that, then a cute anime to teach you about the body is just what you need. We will keep watching this one for sure.
