Detailed explanation-1: -The bronchi are the two large tubes that carry air from your windpipe to your lungs. You have a left and right main bronchus in each lung. After the main bronchi, these tubes branch out into segments that look like tree branches. Many respiratory conditions, such as asthma or bronchitis, can affect your bronchi.
Detailed explanation-2: -The only point of attachment for each lung is at the hilum, or root, on the medial side. This is where the bronchi, blood vessels, lymphatics, and nerves enter the lungs.
Detailed explanation-3: -There are 20-25 branching generations of conducting bronchioles after the tertiary segmental bronchi. As the bronchioles become smaller in width, they become terminal bronchioles which mark the end of the conducting zone of the respiratory system.
