Salt gland of a bird and its inner structure Magellanic penguin. The avian salt gland has two main ducts: a medial and a lateral. Salt gland activations occurs from increased osmolarity in the blood, stimulating the hypothalamic information processing, sending a signal through the parasympathetic nerve activating vasodilation, the release of hormones (acetylcholine and vasoactive intestinal ...
The condition generally mimics symptoms of a viral infection. Fever, malaise and chills are most commonly reported, and usually the first systemic symptoms to appear. Most individuals experience tremors and shivering [1] — the latter is worse with reduced oxygen levels in blood. [7] These symptoms tend to worsen with cold exposure or physical ...
Exposure to oil can reduce penguins' immunity and make them vulnerable to fungus, bacteria and lung problems. [ 19 ] Zoo representatives from around the world have adopted Magellanic penguin hatchlings and bred them in captivity, [ citation needed ] which serves to build insurance populations (though these animals are unable to participate in ...
In the airways of the lung, CFTR is most highly expressed by rare specialized cells called pulmonary ionocytes. [16] [17] [18] In the skin, CFTR is strongly expressed in the sebaceous and eccrine sweat glands. [19] In the eccrine glands, CFTR is located on the apical membrane of the epithelial cells that make up the duct of these sweat glands. [19]

Salt glands also play a major role in the excretion of excess salts. In aquatic birds such as the Adelie penguin, nasal salt glands excrete an extremely concentrated sodium chloride solution, reducing the load on their kidneys. [49] These excretions are crucial in the maintenance of Antarctic ecosystems.
Whole lung lavage (WLL), also called lung washing, is a medical procedure in which the patient's lungs are washed with saline (salt water) by filling and draining repeatedly. It is used to treat pulmonary alveolar proteinosis , in which excess lung surfactant proteins prevent the patient from breathing.
