When the tracheobronchial tree is patent, it means that the airways are open and unobstructed, allowing for the normal passage of air into and out of the lungs. This is essential for proper respiratory function and gas exchange in the body. A patent tracheobronchial tree is crucial for maintaining adequate oxygen levels in the blood and removing carbon dioxide from the body.
It is within the neck and chest
The ciliated epithelium of the tracheobronchial tree helps to remove mucus and foreign particles from the respiratory tract by moving them upwards towards the throat to be either swallowed or expelled. This movement of the cilia helps to protect the lungs from infections and irritants.
The respiratory zone of the tracheobronchial tree includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli where gas exchange occurs. This is where oxygen is absorbed into the bloodstream and carbon dioxide is released from the bloodstream.
Respiratory system has got cilia all over the tracheobronchial tree. This protect the respiratory system from damage.
