The pleura is a thin membrane that lines the surface of the lungs and the inside of the chest wall outside the lungs. In pleural effusions, fluid builds up in the space between the layers of pleura.
Major Landform regions of Australia See also. The Australian continent is broadly divided into 4 major landform regions, each of which is comprised of smaller-scale constituent landform regions-eastern highlands, central lowlands, western plateau and the coastal plains.he lowest point on the Australian continent, Lake Eyre, is also situated in this region. It also includes inselbergs such as Uluru and Kata Tjuta. About 38 % of the Australian continent is less than 200 m above sea level (so far), much of it in the Central lowlands.
It is a low lying, featureless area of the continent, and is an average of 200m above sea level. It has very dry, arid to semi-arid conditions, and although it is quite flat, it does have some mountains. The only feature is Lake Eyre, which is 15m below sea level, and is 10,000 km squared.he Western Plateau is very dry, and mostly desert. There are a few points of interest here, such as; The Great Sandy and Victoria Deserts, Uluru, Kata Tjuta and Kings Canyon. The Central Lowlands has almost nothing of interest, except for Flinders Range, and parts of the Great Artesian Basin.
