The adaptations of blood in terrestrial animals living at high altitude

At high altitude the oxygen tension is very low. Thus, the adaptations of blood are the same as those for the mammal at a low oxygen tension.

The hemoglobin concentration of blood increases. This increases the oxygen carrying capacity of the blood.

The number of red blood cells increases in order to increase the oxygen carrying capacity of the blood.

The hemoglobin/respiratory pigment has a high affinity for oxygen so as to pick up a lot of oxygen
