The adaptation that enables the albatross and other marine birds to maintain internal salt balance is a specialized nasal gland. In removing excess sodium chloride from the blood, the nasal gland relies on __.
- In the albatross' nasal gland, the net result is the secretion of fluid much saltier than the ocean. Thus,e ven though drinking seawater brings in a lot of salf, the bird achieves a net gain of water. By contrast, humans who drink a given volume of seawater must use a greater volume of water to excrete the salt load, with the result that they become dehydrated.
