Meanwhile, the new T-Mobile Arena allows MGM to effectively own the larger events market. It plans to keep the 16,500-seat MGM Grand Garden Arena's schedule full too. The sister venue across the street will continue to host concerts and boxing matches and allow the company's convention business to expand.
The human lungs are a pair of large, spongy organs optimized for gas exchange between our blood and the air. Our bodies require oxygen in order to survive. The lungs provide us with that vital oxygen while also removing carbon dioxide before it can reach hazardous levels.lveoli are the functional units of the lungs that permit gas exchange between the air in the lungs and the blood in the capillaries of the lungs. Alveoli are found in small clusters called alveolar sacs at the end of the terminal bronchiole.
Lungs ensure that efficient gas exchange takes place between the air and the person's blood. The lungs are a pair of lobed s â¦ tructures made up of a series of highly branched tubules called bronchioles, which end in tiny air sacs called the alveoli (the alveolar membrane is the site of gas exchange).  Lungs allow us to take in oxygen from the external air and allow us to get rid of excess carbon dioxide. alveolar = air sac   simple squamous epithelium; single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm; the simplest of the epithelium.
