Cells at Work! (2018)

S01E08 Blood Circulation

Red Blood Cell has a vital job: carrying carbon dioxide to the lungs and oxygen to every cell in the body. She still has a terrible sense of direction and gets lost constantly, but she refuses to stay a rookie forever. She's set on completing the Circulation route all on her own, without relying on the veteran cells. Unbeknownst to her, White Blood Cell (Neutrophil) trails behind in the shadows, keeping watch with an anxious expression.
