The air pressure is lower in a high altitude than at the sea level. This is because at a high altitude, the atmosphere is less and the air molecules are further apart. It is therefore difficult for oxygen to enter the vascular system at a high altitude due to the lower air pressure. During breathing process at sea level, a high atmospheric pressure causes the air to easily pass through our lung membranes into the blood system.At high altitude the lung systems are deprived of oxygen, a condition known as hypoxia.
