Vakagamuchira munguva inspiratory chikamu mhepo anopinda Formação de pakati mumapapu, ayo vakaungana, sezvinoita boka namazambiringa thinnest sepombi - bronchioles. Kubva ropa runodziganhura mamiriro katatu, mumwe Ukobvu 0.1-1.5 microns, rinonzi mhepo-ropa nokuidzivirira. Chinosanganisira alveolar Kamudzira uye cytoplasm kuti zvinhu, zvikamu endothelium uye nemvura mukati. Nokuti kunzwisisa zvakataurwa Formação de uye chii ayo kushanda nani, zvinofanira kurangarirwa kuti diffusion zviri magasi mumapapu hazvibviri pasina zvivako zvakadai interalveolar septum, ropa mhinganidzo, uye interstitium, rine fibroblasts, macrophages uye leukocytes. An basa rinokosha rinoitwa nevanhu alveolar macrophages, alveolar septa akaronga mukati uye pedyo capillaries. Pano achanamatira kune zvinokuvadza nezvimedu vakagamuchira mumapapu panguva inhalation. Macrophages kunogonawo phagocytose masero eropa matsvuku parumananzombe alveolar matema kana munhu nechirwere chemwoyo, vakaremerwa kuzara zviratidzo mumapapu.
