Unscramble the Blue Letters

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 cnutnioe to rise, awliolng your blood to carry even more oxygen per milliliter. Paired with your high heart rate, this new hemoglobin-rich blood efficiently distributes oyexgn throughout your body. So much so that the vlmuoe of blood being pumped with each heartbeat can return to normal lveels. Over this same time, your breathing also increases even further in a process called ventilatory acclimatization.
