pulmonary infiltrate
Emphysema is the irreversible enlargement of the air spaces in the lungs.
The air spaces in the lungs are called pulmonary alveoli. They are where gas exchange occurs in the lungs of mammals.
Mediastinum
Empty spaces within the body are commonly referred to as cavities. These include the cranial cavity (housing the brain), thoracic cavity (housing the heart and lungs), and abdominal cavity (housing the digestive organs). These cavities help protect and support the internal organs.
The branching tubes within the lungs end at small alveoli.
The actual sites of gas exchange within the lungs are the alvioli.
Alveoli are grape-like air spaces at the distal ends of the bronchial upside-down tree.

Lungs are part of the circulatory system within the human body.
The lungs, trachea, and heart do not reside within the mediastinum. They lie outside this region.
