Lymphangioleiomyomatosis
A disease characterized by the progressive invasion of SMOOTH MUSCLE CELLS into the LYMPHATIC VESSELS, and the BLOOD VESSELS. The majority of the cases occur in the LUNGS of women of child-bearing age, eventually blocking the flow of air, blood, and lymph. The common symptom is shortness of breath (DYSPNEA).
Pneumothorax

Air Microbiology
The presence of bacteria, viruses, and fungi in the air. This term is not restricted to pathogenic organisms.
Air Movements
The motion of air currents.
Air Pollution, Indoor
The contamination of indoor air.
Air Sacs
Air Conditioning
The maintenance of certain aspects of the environment within a defined space to facilitate the function of that space; aspects controlled include air temperature and motion, radiant heat level, moisture, and concentration of pollutants such as dust, microorganisms, and gases.
