I would most likely associate this with either pneumonia (acute) or if patient is older some form of COPD; possibly Chronic Bronchitis.
Draining the oceans would show features such as mid-ocean ridges. These features would look like an extensive mountain range running down the spine of the ocean floor. This region marks the area where two oceanic tectonic plates are being pushed apart. Closer to land or the continents would be a gentle shelf that gradually deepens as one moves away from the coastline. This relatively gentle plain would then make a steep drop off down to an extensive plain stretching towards ocean ridges. The ocean floor also supports lone mountain structures, canyons and chasms.

Galapagos islands are groups of island in the pacific ocean that are known to have a wide range of native animals such as giant tortoise that found no where else on earth. These native animals helped Darwin in the development of the theory of natural significance which attributes to the biological significance of the Galapagos islands. Human species is a threat to the natural wildlife on these islands mainly due to poaching and destruction of natural forests that destroys habitat and also impacts negatively on biological diversity of living organisms.
Answer:
The barrier functions to regulate the chemical composition of the extracellular fluid surrounding the brain cells.
Explanation:
Blood-brain barrier
It is a very selective semipermeable membrane , hence allow some specific substance to pass via it . This barrier separates the extracellular fluid in the central nervous system and the circulating blood from the brain .
<u>The barrier is composed of the endothelial cells .</u>
Passive diffusion is shown in this system , and allows molecules like the water , glucose , amino acid to pass .
It regulates the chemical composition of the fluid of brain cell .
