U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Marinka: Cudurka neefta waxaa loo kala saaraa inta jeer ee ay calaamaduhu soo baxaan, heerka neefsashada ee hal ilbiriqsi (FEV1), iyo heerka ugu sarreeya ee neefsashada. Asthma waxaa sidoo kale loo kala saari karaa atopic (extrinsic) ama non-atopic (intrinsic), iyadoo lagu saleynayo in calaamadaha ay keenaan allergens (atopic) ama aan ahayn (non-atopic). Inkastoo cudurka neef-mareenka lagu kala saaro darnaantiisa, haddana ma jiro hab cad oo lagu kala saaro kooxaha hoose ee neef-mareenka oo aan ku jirin nidaamkan. Helitaanka habab lagu aqoonsado kooxaha yar yar ee si fiican uga jawaabaya noocyada kala duwan ee daaweynta ayaa ah hadaf muhiim u ah cilmi baarista cudurka neefta. In kasta oo neefta ay tahay xaalad joogto ah oo xanniban, looma tixgeliyo inay qayb ka tahay cudurka sambabka ee joogtada ah, maadaama ereygan uu si gaar ah u tilmaamayo isku darka cudurrada aan la soo celin karin sida bronchiectasis iyo emphysema. Si ka duwan cudurradaas, xannibaadda waddooyinka neef-mareenka ee cudurka neef-mareenka ayaa sida caadiga ah dib loo soo celin karaa; si kastaba ha noqotee, haddii aan la daaweyn, caabuqa joogtada ah ee neef-mareenka ayaa u horseedi kara sambabada inay noqdaan kuwo aan dib loo soo celin karin sababtoo ah dib-u-habeynta waddooyinka neef-mareenka. Si ka duwan cudurka loo yaqaano emphysema, cudurka neefta ayaa saameeya bronchi, ma saameeyo alveoli.  Suaashu waxay tahay: Waa maxay labada nooc ee cudurka neefta?
atopic (extrinsic) ama aan atopic ahayn (intrinsic)
