Elephant Anatomy - Respiratory System2015
By Amelia Meyer
Owing to the sheer size of the magnificent elephant, certain adaptations have had to be made respecting their respiratory system. Mammals usually share the common trait of a pleural cavity; the space between the pleura, in which the lungs are situated. This lubricated membrane, the pleura, usually aids in respiration by exerting negative pressure on the lungs and thereby forcing them to expand so that the host can inspire (breathe in). However, elephants do not have this cavity. Rather, their ample lungs are attached directly to the chest cavity wall and the diaphragm. Elephants will breathe out an average of 310 litres of air every minute!
