1. Pulmonary ventilation – the activity of breath to move air into and also out the the lungs. (‘Pulmonary’ refers to the lungs).

2. Pulmonary gas exchange – the exchange the O2 and CO2 in between the blood and also the lungs. This is likewise known together ‘external respiration’.

3. Respiratory gas transport – the communication of the respiratory system with the cardiovascular system to carry O2 and CO2 in between the lungs and the organization of the body.
