A. Glass tile is renowned for its versatility. Because it is impervious to the effects of moisture, glass tile is a popular addition to bathroom areas and spa locations in commercial settings as well as residential ones. Glass tile can be used as a wall tile to cover surfaces entirely, or as flourishes and trim pieces. They can be used for shower stall floors, and as creative centerpieces to a room in the form of murals or as unique layouts that mix colored glass tiles in a mosaic pattern.
The alveolar oxygen partial pressure is lower than the atmospheric O 2 partial pressure for two reasons. 1  Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 mmHg) reduces the oxygen partial pressure to about 150 mmHg.
Pulmonary alveolus. An alveolus (plural: alveoli, from Latin alveolus, little cavity) is a hollow cavity found in the lung parenchyma, and is the basic unit of respiration. Lung alveoli are the ends of the respiratory tree, branching from either alveolar sacs or alveolar ducts, which like alveoli are both sites of gas exchange with the blood as well. Alveoli are particular to mammalian lungs. Different structures are involved in gas exchange in other vertebrates. The alveolar membrane is the gas exchange surface. Carbon dioxide rich blood is pumped from the rest of the body into the capillaries that surround the alveoli where, through diffusion, carbon dioxide is released and oxygen absorbed.
