The respiratory system brings air from the atmosphere into the lungs. The trachea– the tube connecting the throat to the bronchi. As such, bronchioles are one of the smallest airways in the respiratory tract, and lead directly to the alveolar ducts which house the alveoli responsible for exchanging gases with the blood. These bronchi then go on to divide into smaller bronchi. The bronchioles are tubes in the lungs which branch off from the larger bronchi that enter each lung, from the large and singular trachea which connects to the mouth.
