The amount of gas remaining in lungs after normal expiration

In obstructive lung disease

During inspiration, thoracic spine extends enabling greater excursion of the sternum

Transverse diameter can be increased by

During inspiration, angle at costochondral junction increase making ribs segments shorter

During inspiration, vertical dimention can be increased by

Breathing exercises can make adequate gases available but can't change the physiology of gas exchange

In asthma, airflow resistance will be Greater than normal during expiration

As the diameter of the airway decrease, the resistance to airflow decrease

Cough is also called tussis

Cough is slow expulsion of air from the lungs typically in order to clear the lungs of fluids and mucus
