Bronchi
The bronchi are the main passageways directly attached to the lungs. The bronchi branch from the trachea and lead air into the lungs.
Anatomy of Bronchi
The bronchi are made up of cartilage and smooth muscle. They are lined with mucus-producing cells and hair-like structures called cilia, which help to trap and remove particles from the air before it reaches the lungs.
Function of Bronchi
The bronchi serve as the main conduits for air to enter and exit the lungs. They also help to humidify, warm, and filter the air before it reaches the delicate lung tissue.
