Abstract
Mazkur ilmiy maqolada 1–3 yoshli bolalarda o‘pka bronxlarining postnatal ontogenez jarayonidagi morfologik va funksional rivojlanish ko‘rsatkichlari tahlil qilinadi. Ilk bolalik davri nafas tizimi uchun intensiv o‘sish va differensiallanish bosqichi bo‘lib, bronx devorlarining qalinlashuvi, epiteliy hujayralarining yetilishi, silliq mushak qavatining rivojlanishi hamda alveolyar apparatning kengayishi bilan tavsiflanadi. Tadqiqot natijalari ushbu davrda bronxlar strukturaviy va funksional jihatdan yuqori plastiklikka ega ekanini ko‘rsatadi. Olingan ma’lumotlar pediatriya va bolalar pulmonologiyasi amaliyotida muhim ahamiyat kasb etadi.
