[{"id":37830,"question":"Quel organe joue un rôle central dans la régulation de la pression artérielle ?","option_a":"Le foie","option_b":"Le cerveau (bulbe rachidien)","option_c":"Les reins","option_d":"Le pancréas","option_e":"","option_f":"","bonne_reponse":"b","explication":"Le bulbe rachidien, situé dans le tronc cérébral, intègre les signaux des barorécepteurs et ajuste le

?","option_a":"L'insuline","option_b":"L'adrénaline","option_c":"L'ocytocine","option_d":"La thyroxine","option_e":"","option_f":"","bonne_reponse":"b","explication":"L'adrénaline, sécrétée par les glandes surrénales, provoque une vasoconstriction et augmente le rythme cardiaque, augmentant ainsi la pression artérielle.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"L'insuline\",

système nerveux parasympathique.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai : le système nerveux parasympathique (responsable du ralentissement du cœur) est inhibé pour permettre une augmentation de la pression artérielle.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\":

?","option_a":"Augmentation","option_b":"Diminution","option_c":"Stabilisation","option_d":"Aucun effet","option_e":"","option_f":"","bonne_reponse":"b","explication":"La vasodilatation réduit la résistance vasculaire, ce qui diminue la pression artérielle.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Augmentation\",

sanguin.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai : les reins régulent la pression artérielle en ajustant la réabsorption d'eau et de sels, influençant ainsi le volume sanguin.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\":

?","option_a":"Une augmentation de la fréquence respiratoire","option_b":"Une vasoconstriction réflexe","option_c":"Une sécrétion accrue de bile","option_d":"Une dilatation des pupilles","option_e":"","option_f":"","bonne_reponse":"b","explication":"Le corps active une vasoconstriction réflexe pour rétablir rapidement la pression artérielle.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Une augmentation

par les reins.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"Faux : l'ADH augmente la réabsorption d'eau par les reins, augmentant ainsi le volume sanguin et la pression artérielle.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Vrai\", \"b\":

diminution","option_b":"Une augmentation","option_c":"Une stabilisation","option_d":"Aucun effet","option_e":"","option_f":"","bonne_reponse":"b","explication":"L'exercice physique intense augmente la pression artérielle pour répondre aux besoins accrus en oxygène des muscles.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Une diminution\",

nerveux.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai : la régulation à court terme (quelques secondes à minutes) est principalement assurée par le système nerveux autonome.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\":
