This is a story about you. A tale about the inside of your body... According to a new study, the human body consists of approximately 37 trillion cells. These cells are hard at work every day within a world that is your body. From the oxygen-carrying red blood cells to the bacteria-fighting white blood cells, get to know the unsung heroes and the drama that unfolds inside of you! It's the oddly relatable and interesting story that is the life of cells!

Biology the Animation. Nuff said.

Hataraku Saibou has more than just the overwhelming fanbase: it actually brought non-otakus and people who don't watch anime to come and watch this fascinating piece of work that honestly isn't like any other anime out there. With that said, this is easily AOTS for many people come in not expecting anything and then being surprised by what it does and adds to the overall presentation.

This is the story about all of us: the system within the human body, the innards, effects and all the hoopla that's going on in our bodies, from as simple as the protecting red and white read more

(I’ll only be keeping my review short and brief as only 4 episodes have been released as I write this)

As a nursing student who has had to take microbiology, anatomy, and immunology classes and such I have to say I'm quite surprised as to how accurate and informative this anime is whilst being able to have a laugh at the way they portray formed elements and bacteria as characters and the landscape of the different transportation systems and organs in the body.

This anime is great and I highly recommend it to anyone, especially if you're looking to learn about cell biology-although I believe it'd read more

Cells At Work is an educational series about how the human body functions on cellular level. Its source material was originally released in the Japanese science magazine called Gross Biological Stuff and Geeky Nerdy Shit Weekly, now made into an anime format to ensure the misinformation of this shonen comedy reaches a wider audience.

I refuse to use the reddit meme phrase ""as a" biology major" to back up my rhetoric with titles -- moreover, majoring biology requires bit more than reading 3 wikipedia articles about cells -- so instead I will say this series has a pretty interesting take on something that could be read more

As the last third of 2018 draws near, we find ourselves right in the middle of a superb Summer season where various well-received returning anime fight for the position of best show of the cour and, by extension, of the year, all of them with very high ratings. However, new releases are also holding up competently, with new adaptations of classic and recent media and its fair share of originals. And among the new names of Summer 2018, one of the biggest is Hataraku saibou (Cells at Work!), already one of the most commented shows over the course of the last weeks. Brought to life read more
