哮喘发作病人支气管树模型


通过粘液和模仿咳嗽建立哮喘发作时病人的支气管树模型。粘液由支气管粘膜下腺的肥大细胞分泌,支气管收缩,以及粘液脱水浓缩来形成粘液栓,阻塞哮喘病人气道。
This cast of the bronchial tree is formed of inspissated mucus and was coughed up by a patient during an asthmatic attack. The outpouring of mucus from hypertrophied bronchial submucosal glands, the bronchoconstriction, and dehydration all contribute to the formation of mucus plugs that can block airways in asthmatic patients.
