The Body's Sentinels (E03)

Today we learn about the sentries of the body, or more precisely, the white corpuscles. The story’s set in the thymus school, where Colonel Peter is giving a lecture for a young lymphocyte class. Thereby, he explains the importance of knowing the body’s enemies: bacteria, viruses, dust particles and toxins. Colonel Peter introduces the defense unit of the body: Scout Peter and companion Pierrette, who watch for intruders and policeman Jumbo, who directly fights the enemies, and many other important people.
