Ventilation
Respiration
What is a long-term effect of exercise on the respiratory muscles
Decreases the strength of the diaphragm
Decreases the strength of the intercostal muscles
Increases the strength of the diaphragm
Increases the strength of the intercostal muscles
Vital Capacity is
The amount of air we breathe in and out at rest
The amount of air we breathe in and out during exercise
The maximum amount of air we can expire after maximal inhalation
The maximum amount of air we can inspire after taking a deep breath in

Asthma is...
a disorder characterized by low bone mass, leading to bone fragility, and consequent increase in fracture risk.
a medical condition in which a person's spine has a sideways curve. The curve is usually "S"- or "C"-shape.
a common condition where airways can become restricted. The tightening of the muscles surrounding the trachea prevent gases from freely moving in or out.
a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level.
