They are integral to the respiratory system and are protected by the ribcage. Each lung is divided into lobes: the right lung has three lobes, while the left lung has two, leaving room for the heart. The lungs are made up of tiny air sacs called alveoli, where oxygen is exchanged for carbon dioxide during respiration. These alveoli are connected to a network of branching tubes called bronchi and bronchioles, forming a complex tree-like structure. #Wanderlust #TravelGoals #AdventureAwaits #FitLife #WorkoutMotivation #MindAndBody #Foodie #HealthyEating #TastyTreats #StyleInspo #MakeupLover #OOTD #SaveThePlanet #NaturePhotography #WildlifeLovers #SupportSmallBusiness #HustleHard #DreamBig #FutureTech #AIRevolution #Innovation #PositiveEnergy #LiveYourBestLife #LifeGoals #GamingCommunity #GameOn #FunTimes #BeautifulGirls #DreamBig #ChasingDreams #DreamLife #GamingFun #GamerGirl #BeautyAndBrains #FantasyWorld #Dreamscape #PlayMore #GameNight
