Inhalation and exhalation
The movement of air on and out the lungs is called respiration. The movement of air into the lungs is called inhalation (inspiration). The movement of air out of the lungs is called exhalation (expiration).
Inhalation and exhalation
The movement of the chest that brings air into the lungs is called inhalation, and it is facilitated by the contraction of the diaphragm and intercostal muscles. Exhalation is the process of removing waste gases from the lungs, which is typically a passive process where the diaphragm and intercostal muscles relax.
hyperventilation
It is called breathing. Breathing is the movement of the chest that brings air into the lungs and removes waste gases. The air entering the lungs contain oxygen. It passes from the lungs into the circulatory system because there is less oxygen in blood when it enters the lungs than in the cells of the lungs.

The air left in your lungs after exhaling is called "Expiratory Reserve".
When your lungs move to bring in air and remove gases you are breathing.
Inhalation and exhalation
When air passes through your lungs it is called respiration.
The air spaces in the lungs are called pulmonary alveoli. They are where gas exchange occurs in the lungs of mammals.
it is called air sacks
Birds lungs are called lungs but birds also possess air sacs for help in respiration .
