[{"id":119147,"question":"Quel nerf est principalement responsable de la bronchoconstriction ?","option_a":"Nerf vague (parasympathique)","option_b":"Nerf phrénique","option_c":"Nerf sympathique","option_d":"Nerf spinal","option_e":"","option_f":"","bonne_reponse":"a","explication":"Le nerf vague (parasympathique) libère de l’acétylcholine, provoquant une contraction des muscles lisses des bronches, donc une bronchoconstriction.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Nerf vague (parasympathique)\", \"b\": \"Nerf phrénique\", \"c\": \"Nerf","_debug_options_count":4},{"id":119148,"question":"La bronchomotricité permet de réguler le diamètre des bronchioles.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai.

L’adrénaline, hormone du stress, active les récepteurs bêta-2 adrénergiques, entraînant une bronchodilatation pour faciliter la respiration.","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\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":119151,"question":"Quel est le rôle principal des alvéoles dans la ventilation ?","option_a":"Filtrer l’air inspiré","option_b":"Échanger les gaz (O2 et CO2)","option_c":"Stocker l’oxygène","option_d":"Produire du mucus","option_e":"","option_f":"","bonne_reponse":"b","explication":"Les alvéoles sont le siège des échanges gazeux entre l’air inspiré et le sang, permettant l’oxygénation et l’élimination du CO2.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Filtrer l’air inspiré\", \"b\": \"Échanger les gaz (O2 et CO2)\", ","_debug_options_count":4},{"id":119152,"question":"La bronchite chronique entraîne une réduction permanente du diamètre des bronches.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai. La bronchite chronique provoque une inflammation et un épaississement des parois bronchiques, réduisant leur diamètre de manière permanente.","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\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":119153,"question":"Quel muscle principal intervient dans l’inspiration ?","option_a":"Muscle intercostal","option_b":"Diaphragme","option_c":"Muscle sternocléidomastoïdien","option_d":"Muscle abdominal","option_e":"","option_f":"","bonne_reponse":"b","explication":"Le diaphragme est le muscle principal de l’inspiration : sa contraction augmente le volume de la cage thoracique, permettant l’entrée d’air dans les poumons.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Muscle intercostal\", \"b\": \"Diaphragme\", \"c\": \"Muscle sternocléid","_debug_options_count":4},{"id":119154,"question":"La bronchoconstriction est toujours pathologique.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"Faux.
