What happens to body tissue at higher elevations?

At higher elevations, the atmospheric pressure decreases, which leads to a reduction in the amount of oxygen available in the air. As a result, body tissues receive less oxygen compared to lower elevations. This reduced oxygen availability can affect various bodily functions and may lead to symptoms associated with altitude sickness, such as headache, fatigue, and shortness of breath. The body may begin to acclimatize over time by producing more red blood cells or increasing respiratory rate, but initially, the availability of oxygen to tissues is significantly lower. This physiological response is crucial for understanding how the body adapts to changes in environment and altitude.
