The function of the respiratory system in the respiratory process is to breathe.
The respiratory system functions for the conduction of air that is rich in oxygen into the lungs and the removal of air rich in carbon dioxide to the outside.
The respiratory system facilitates the exchange of gases through processes such as breathing, inhalation as well as exhalation occurring between the air and blood and also between the blood and body cells. The respiratory system also helps in sensing smell and creating sounds.
The respiratory system controlling breathing is also termed pulmonary ventilation. In the case of pulmonary ventilation, the air is inhaled through the nasal as well as oral cavities. It then moves through the pharynx, larynx, and trachea and finally into the lungs.
Then it is followed by the exhalation of air, which will be flowing back through the same pathway where inhalation occurs. Pulmonary ventilation is triggered by changes in volume and air pressure in the lungs.
During normal inhalation, contraction of the diaphragm and external intercostal muscles takes place and then the ribcage elevates.

Answer:
All livings organisms are with unicellular origin. The cells have a common structure like cell membrane, DNA , RNA and necessary enzymes. The genetic code of protein synthesis is almost similar with few exceptions. This shows unity in design.
Further evolutionary changes took place due to environmental stress. The genome of each species is designed as per need and efficiency. This is diversity.
This is true with all five kingdoms of life that is monera, protista, fungi, plantae and animalia.
