... The epiglottis directs air down the trachea, which is the most direct pathway to the lungs. The lungs are not hollow sacs but are instead filled with folds of tissue that greatly increase surface area. Bronchus run along the folds and branch into bronchioles which have alveoli attached to them. ...

... Insects do not have the problem of losing too much water by evaporation through their respiratory membrane because it is located inside their body. A tracheal system, consisting of branching respiratory tubes, connects cells directly to the atmosphere by openings in the exoskeleton called spiracles ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
