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.
The alveoli are grouped together like a lot of interlinked caves, rather than existing as separate individual sacs. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues. Carbon dioxide produced by the bodyâs metabolism returns to the lung via the blood. It then diffuses across the capillary and alveolar walls into the air to be removed from the body with expiration. The alveoli have a structure specialised for efficient gaseous exchange: Walls are extremely thin.
