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.
There are about 300 million alveoli in a normal lung. When the air that you've just breathed in reaches these air sacs, the oxygen in the air passes through the air sac walls into the blood in the capillaries.At the same time, carbon dioxide (a waste gas) moves from the capillaries into the air sacs.This process is called gas exchange. The oxygen-rich blood in the capillaries then flows into larger veins, which carry it to the heart.here are about 300 million alveoli in a normal lung.
