From the Ted Talk by Andrew Lovering: How high altitude affects your body
Unscramble the Blue Letters
Within the first few days above 1,500 meters, the volume of pmasla in your blood decreases, which increases the concentration of hemoglobin. Over the next two wkees, your hemoglobin levels will continue to rise, allowing your blood to carry even more oxygen per milliliter. Paired with your high heart rate, this new hemoglobin-rich blood ecieffinlty distributes oexygn throughout your body. So much so that the volume of blood being pempud with each heartbeat can return to normal levels. Over this same time, your breathing also ienesrcas even further in a process called ventilatory acclimatization.

Original Text
Within the first few days above 1,500 meters, the volume of plasma in your blood decreases, which increases the concentration of hemoglobin. Over the next two weeks, your hemoglobin levels will continue to rise, allowing your blood to carry even more oxygen per milliliter. Paired with your high heart rate, this new hemoglobin-rich blood efficiently distributes oxygen throughout your body. So much so that the volume of blood being pumped with each heartbeat can return to normal levels. Over this same time, your breathing also increases even further in a process called ventilatory acclimatization.
