Créer un schéma éducatif simple et coloré sur la circulation des gaz respiratoires chez l’humain. Montrer les poumons, le sang et les cellules. Utiliser des flèches rouges pour le CO₂ qui part des cellules vers les poumons, et des flèches bleues pour l’O₂ qui va des poumons vers les cellules. Ajouter des légendes claires : 'O₂', 'CO₂', 'Poumons', 'Sang', 'Cellules'. Style clair, pédagogique et facile à comprendre pour des étudiants. Mehr sehen
