👉 The term "bronchi" generally refers to airways in the lungs. These are tubes that carry air from the lower part of the body, such as the chest and back, through the nose, mouth, and throat, to the lungs where it is taken up by the bloodstream for oxygenation.
Bronchi are also known as bronchioles, which are smaller airways that are lined with纤毛细胞。 These cells help to filter out dust, smoke, and other particles from the air
