Health Educational Cartoon series, with blood cells walking around carrying O2 and chit chatting. Tittle?

1980's Health/Educational Cartoon series, with blood cells walking around carrying O2 and chit chatting. Antibody in the form of Sheriffs (with gold stars on chest) wearing all white uniform shooting or swallowing the bacterias and viruses. Basically the animation educate children on our body functions. I think it was a production from a European country but i can't remember. I saw it in Malaysia / Singapore dog years ago in the 1980s. What was the tittle?
