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 ...
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.
The Magellanic penguin ... Their salt-excreting gland rids the salt from their bodies. Adult penguins can regularly dive to depths of 20 to 50 m (66 to 164 ft) deep ...
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.
The mucosa-associated lymphoid tissue (MALT), also called mucosa-associated lymphatic tissue, is a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, nasopharynx, thyroid, breast, lung, salivary glands, eye, and skin.
Gentoo penguins can reach a length of 70 to 90 cm (28 to 35 in), [19] [20] making them the third-largest species of penguin after the emperor penguin and the king penguin. Males have a maximum weight around 8.5 kg (19 lb) just before moulting and a minimum weight of about 4.9 kg (11 lb) just before mating.
Pierre hatched at the Maryland Zoo in Maryland in 1983 and was transferred in June to the Steinhart Aquarium facilities at the CAS. In 1997, the then-14-year-old Pierre began coughing periodically, due to an allergic reaction inflaming the upper respiratory tract, treated with one or two daily doses of hydroxyzine.
The gland secretes highly concentrated brine stored near the nostrils above the beak. The bird then "sneezes" the brine out. As freshwater is not usually available in their environments, some seabirds, such as pelicans , petrels , albatrosses , gulls and terns , possess this gland, which allows them to drink the salty water from their ...
