NB: Gas exchange is the process by which oxygen reaches cells
... Organisms are differently adapted so gas exchange can take place whether it be in water or on land. In particular oxygen is needed to convert organic molecules into energy through the process of respiration. NB: Gas exchange is the process by which oxygen reaches cells and waste products are removed ...

Metabolism of Oxygen

Because oxygen is one of the major substances required for chemical reactions in the metabolism, it is fortunate that the human body has special control mechanisms which maintain almost constant oxygen concentration in the extracellular fluid. This mechanism depends principally on the chemical chara ...

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.
