An alveolus (plural: alveoli, from Latin alveus, "little cavity"), is an anatomical structure that has the form of a hollow cavity. Mainly found in the lung, the pulmonary alveoli are spherical outcroppings of the respiratory bronchioles and are the primary sites of gas exchange with the blood.

English: The respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body. Other languages: Afrikaans : Die asemhalingstelsel bestaan uit lugweë, die longe en die respiratoriese spiere wat lugbeweging in en uit die liggaam reguleer

The posterior and anterior air sacs are also indicated, but not to scale.
Cigarettes are known to cause many lung diseases including emphysema, chronic bronchitis, and lung cancer. Smoker's macrophages are alveolar macrophages whose characteristics, including appearance, cellularity, phenotypes, immune response, and other functions, have been affected upon the exposure to cigarettes.

Pulmonary alveolar microlithiasis is a rare lung disorder of small stone formation in the alveoli. Several factors, including smoking, viral infections, and aging, contribute to physical damage to type II alveolar cells.
The lungs are not capable of expanding to breathe on their own, and will only do so when there is an increase in the volume of the thoracic cavity. [71] This is achieved by the muscles of respiration, through the contraction of the diaphragm, and the intercostal muscles which pull the rib cage upwards as shown in the diagram. [72]
The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
