Inside the human body, roughly 37.2 trillion cells work energetically 24 hours a day and 365 days a year. Fresh out of training, the cheerful and somewhat airheaded Red Blood Cell AE3803 is ready to take on the ever-so-important task of transporting oxygen. As usual, White Blood Cell U-1146 is hard at work patrolling and eliminating foreign bacteria seeking to make the body their new lair. Elsewhere, little platelets are lining up for a new construction project.

Dealing with wounds and allergies, getting lost on the way to the lungs, and bickering with similar cell types, the daily lives of cells are always hectic as they work together to keep the body healthy!

"The human body is the best work of art." - Jess C. Scott

Science is the study of everything around us. From the early stages of our universe, to the ancient civilizations in the past that leads us to our modern and technological society. Then we come to society. What makes a society even? The people. Humanity have transcended and evolved for generations and generations and will continue evolving like an endless cycle of life.
What does a human compose of? Cells, organs, organ system, tissues, atoms, molecules, ions and so on and so forth. This things, particularly the cells, are the ones that keeps on giving read more

It’s almost impossible to ignore biology when it comes to the human body. Hataraku Saibou (Cells at Work!) has the confidence to be its own series. It’s like you take the cartoony Osmosis & Jones and turns it into an educational exploration. The human body is complex and that alone really made me wonder how this show could capture its magic.

I’d say making this show takes a creative mind and the audience should feel connected when watching this anime. Right from the start, the show reveals the human body and what it’s made up of which is essentially red blood cells. It takes place in read more

This series was one of the most unique ones that most have been anticipating since the start of the year, and when it arrived in the lackluster Summer season, aside from the certainty that does not disappoint, it is entertaining to the mildest degree, while having a lot of *pokes* at the function of the most important system: us human beings.

Now, I don't care that whether you have studied subjects that are close to this, but I'm fairly certain that no matter our background as people whom have learned about cells in one way or another, Hataraku Saibou, or Cells at Work!, will definitely please read more

The Summer season of 2018 seemed to rely heavily on original adaptations when compared to the previous seasons of the same year, especially Spring, when more than half of the top ten most popular anime on this site were sequels. Various well-received returning and continuing anime fought for the position of best show of the cour, all of them with very high ratings; but new releases also held up competently, bringing both classic manga and recent visual and light novels to the screen, along with its fair share of originals. Among the new names of Summer 2018, Hataraku Saibou (Cells at Work!) deservedly warranted much read more
