Air is inhaled through the nose (nasopharynx) or mouth (oropharanx) and travels down the pharynx past the epiglotis and into the larynx. Then down into the Trachea where it meets the Carina and goes either right or left into the Broncus. Then down to the Bronchi and finally the alveoli where gas exchange takes place with the pulmonary capilaries.
The human respiratory system has several mechanisms to get rid of inhaled dirt. These include the presence of mucus and cilia in the respiratory tract that trap and sweep away dirt particles, coughing to expel larger particles, and the body's immune response to help clear any remaining foreign particles.
they permit exchange between the external atmosphere and the circulatory system.
I sincerely suggest that you should describe your question more specifically because diseases of many kinds could have developed in human respiratory system and I don't know what problem is bothering you.
human respiratory uses air pressure like pneumatic system does

The organ that is part of the frog's respiratory system that is not found in the human respiratory system is the skin. The skin is not involved in human respiration.
The respiratory system
the respiratory system in the human body helps humans breathe. that includes lungs, trachea, and more.
The respiratory system starts at the nose (and mouth) and ends at the alveoli in the lungs
Images of the human respiratory system can be viewed on several websites. Among these is Teach PE. Google Images also has many images of the human respiratory system.
The part of the human respiratory system that adds moisture to dry air is the nasal cavity. The nasal cavity is lined with mucous membranes that help humidify and warm the air as it is inhaled, ensuring that the air reaching the lungs is adequately moist. This function is crucial for maintaining the health of the respiratory tract and facilitating gas exchange.
