Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Superheated molten lava, about 2,200 degrees Fahrenheit, is about to explode into the water at the West Mata volcano along the Pacific Ring of Fire.
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.The bronchioles eventually end in clusters of microscopic air sacs called alveoli. Sarcoidosis: Tiny areas of inflammation can affect all organs in the body, with the lungs involved most of the time. 2  The symptoms are usually mild; sarcoidosis is usually found when X-rays are done for other reasons. 3  Obesity hypoventilation syndrome: Extra weight makes it difficult to expand the chest when breathing.
