... Red blood cells are the oxygen carrying cells and are produced by the bone marrow. Hemoglobin, the oxygen carrying compound, makes up 95% of the RBC’s dry weight. Oxygen enters the blood by diffusion across lung membranes. Once in the blood, almost all the oxygen is transported by the hemoglobin loc ...

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.
