High Altitude: How Lowlanders and Tibetans Adapt Differently

Two groups of people climbing a high mountain. One group is from the lowlands, and the other is from the highlands of Tibet. Both groups are going to the same height of 4, 300 meters. Scientists wanted to see how their bodies adjust to the thin air. Lowlanders, or people from the lowlands, started breathing faster to get more oxygen. This made their blood a bit too basic, or alkaline. Their kidneys tried to fix this, but only did a partial job. Tibetans, on the other hand, also breathed faster. But their kidneys did a better job of balancing their blood chemistry. Their blood stayed neutral, showing full compensation. When they reached 4, 300 meters, lowlanders had less carbon dioxide and bicarbonate in their blood, and their blood was more basic. Tibetans had similar changes but kept their blood neutral, showing better adaptation. This shows that Tibetans might have evolved over time to handle high altitudes better. It also highlights how important kidneys are in helping our bodies adjust to thin air.
