Lipids of lung and lung fat emboli of the toothed whales (Odontoceti)
Abstract Lipids are biomolecules present in all living organisms that, apart from their physiological functions, can be involved in different pathologies. One of these pathologies is fat embolism, which has been described histologically in the lung of cetaceans in association with ship strikes and w...
