In common terms, the ventilation cycle is known as “Breathing” and its cycle is in and out movement of air from the lungs. Inspiration is defined as airflow inside the lung and expiration is when the air leaves the lungs with a small pause between inspiration and expiration known as the rest period.
For the body to get oxygen and expel carbon dioxide, inspiration (breathing in) and expiration (breathing out) are essential actions. Expiration is often passive unless it is pushed, whereas inspiration involves the active contraction of muscles, such as the diaphragm.
