Animal euthanasia (euthanasia from Greek: εὐθανασία; "good death") is the act of killing an animal humanely, most commonly with injectable drugs. Reasons for euthanasia include incurable (and especially painful) conditions or diseases, [ 1 ] lack of resources to continue supporting the animal, or laboratory test procedures.
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
A euthanasia solution is a drug-containing aqueous solution for intentionally ending life to either relieve pain and suffering or execute convicts. [1] The drugs used in euthanasia solution do not only need to be safe to personnel, but they also need to have a rapid onset of action and minimize the possible pain felt by humans and animals. [ 2 ]
The experiments start with a dog's heart, attached to a set of tubes to serve as substitutes for the great vessels. Using a system to supply it with blood, the heart beats in the same manner as if it were inside a living organism. The film then shows a lung in a tray, which is operated by bellows that oxygenate the blood being sent to the heart ...
Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .
Although total liquid ventilation (TLV) with completely liquid-filled lungs can be beneficial, [9] the complex liquid-filled tube system required is a disadvantage compared to gas ventilation—the system must incorporate a membrane oxygenator, heater, and pumps to deliver to, and remove from the lungs tidal volume aliquots of conditioned perfluorocarbon (PFC).
ARDS is a form of fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

Mucociliary clearance (MCC), mucociliary transport, or the mucociliary escalator describes the self-clearing mechanism of the airways in the respiratory system. [1] It is one of the two protective processes for the lungs in removing inhaled particles including pathogens before they can reach the delicate tissue of the lungs.
