Antarctic regions (sh) and kidney transplant (sh)


Antarctic regions (sh)




Antarctica and the southern waters of the Pacific, Atlantic, and Indian oceans (the term "Antarctic Ocean" is sometimes used, inappropriately).

Much of the area is characterized by subpolar conditions; ice shelves and sea ice extend well beyond the borders of the continent. The greatest recorded depth is 21,043 ft (6,414 m). Water cooled by the coastal ice masses of the Antarctic continent sinks and flows northward along the ocean bottom and is replaced at the surface by warmer water flowing south from the Indian, Pacific, and Atlantic oceans. The meeting point of these currents is the Antarctic Convergence, an area rich in phytoplankton and krill, which are important to various species of fish as well as to penguins and seabirds.


kidney transplant (sh)




or renal transplant

Replacement of a diseased or damaged kidney with one from a living relative or a legally dead donor.

The former's tissue type is more likely to match, reducing the chance of rejection; but removal puts the donor at risk, and a kidney from a dead donor is more likely to be available. The new kidney is implanted and its blood vessels and ureter sewn in place. A near-normal life may be resumed within two months, but the drugs that prevent rejection leave the patient vulnerable to infection. See also transplant.
