Bronchi

Return to Respiratory System Menu

The bronchi are two large tubes that carry air from the windpipe to the lungs. The bronchi are a crucial part of the respiratory system. They function primarily as passageways for air, bringing oxygen into the lungs and expelling carbon dioxide.

The bronchi are an extension of the trachea and serve as the central passageway into the lungs. Together, these two structures form the tracheobronchial tree of the lungs.

The bronchi branch out into segments that look like tree branches.

The bronchi branch off into smaller bronchi and even smaller tubes called bronchioles. At the end of each bronchiole are tiny air sacs called alveoli. This is the place where the exchange of oxygen and carbon dioxide actually happens.

Many respiratory conditions, such as asthma or bronchitis, can affect your bronchi.
