Aoa! MY name Is Ehsan and welcome to Biology with Ehsan

In this lecture we discussed the structure of lungs externally. In the lungs anatomy there two lobes in left lung which are superior and inferior lobes and three lobes in the right lung which are superior,middle and inferior lobes. Lungs are enclosed by pleural membranes while air passages, arteries,veins and nerves enter into lungs through hilum which is a triangular depression in both lungs. External structure of lungs is a topic in biology class 12 chapter 1 which is about respiration
