In the last few decades, Egyptian higher education has faced many challenges, including a marked increase in students' numbers, insufficient necessary capabilities to develop educational processes, high costs of educational fees in private universities, and emergency circumstances especially during time of national crisis like the COVID-19 pandemic. Many educational institutions consider E-learning as a possible solution for many educational challenges via its advantages that not found in traditional teaching methods.
In response to such challenges, the present study, created electronic learning modules for teaching the donkey's trachea and comparative study of the bronchial trees in domestic animals.
 To perform this study, the study was conducted on the lower respiratory system of ten donkeys of varying ages (3 to 5 years), as well as five sets of lungs and tracheas from buffalos, goats, camels and dogs. Theses specimen were subjected to variable anatomical techniques. For interactive and e-learning concepts, computer programs were used.
The present work concluded that the lower respiratory portions begins from the cricotracheal junction and the trachea of the donkey consists of 49-51 hyaline incomplete cartilaginous rings. The bronchial tree follows the lobation of the lung and each lobar bronchus supplied the corresponding lung lobe. Although great student's ratio was mostly satisfied with e-learning evaluation survey. However, noted technical issues with internet connectivity and IT facilities, so we recommended by using blended learning to overcome the cons of e learning.
