Which of these are restrictive: obstructive pulmonary diseases are asthma, chronic bronchitis and emphysema?

Pulmonary: All the pulmonary fibrosis diseases are restrictive as are the infiltrative diseases.

Obesity, fibrosis: Restriction is defined as low lung volumes. Less air "capacity" of the lung . Less air moves into the lung. A "thick" chest wall ( obesity), , poorly functioning respiratory muscles are some reasons. Pulmonary fibrosis is another distinct category. "fibrosis" disorders are varied and are described as interstitial lung disease

Restriction: Airway "obstruction" refers to limitation of air flow through the airways. "restriction" refers to processes that keep the lungs from opening fully when you inhale. Restriction can result from fibrosis, or thickening, of the lung as with diseases like idiopathic pulmonary fibrosis. It can even be from something as simple as obesity or muscle weakness that keeps you from breathing deeply.
