Question

Low concentration of oxygen in the blood and tissues of people living at high altitude is due to:
A) low temperature
B) low atmospheric pressure
C) High atmospheric pressure
D) Both low temperature and high atmospheric pressure

Answer 1

The pressure of circulating blood against the walls of blood vessels is known as blood pressure. The heart pumps blood through the circulatory system, which causes the majority of the pressure. The term "blood pressure" refers to the pressure in the large arteries when used without qualification.

Complete answer:
Low oxygen saturation levels or desaturation of an individual's blood can occur at high altitudes. Low atmospheric pressure at high altitudes causes this to happen. The extent to which hemoglobin is bound or saturated to oxygen is referred to as oxygen saturation levels.

The extent to which hemoglobin is bound or saturated to oxygen is referred to as oxygen saturation levels. A pulse oximeter is a small device that measures oxygen saturation and pulse/HR. The index finger is the most common location for this device. Normal oxygen saturation levels range from 95% to 100%. Saturation levels of oxygen below 90% are considered abnormal.

Low atmospheric pressure causes low oxygen concentrations in the blood and tissues of people living at high altitudes. Because the partial pressure of oxygen at high altitude is lower than at ground level. The release of oxygen from the blood is caused by the lower atmospheric pressure.

The pressure within Earth's atmosphere, also known as atmospheric pressure or barometric pressure, is called atmospheric pressure. The standard atmosphere is a pressure unit defined as 101,325 Pa, which is equivalent to 760 millimeters of mercury, or 14, 696 pounds of pressure.

Thus, the answer is option B: Low atmospheric pressure.

Note:
Mount Everest, at 29029 feet above sea level, is the highest mountain on the planet. It is located at a very high elevation. These three altitude zones correspond to various levels of low oxygen in the air. Although the atmospheric pressure on Mount Everest is around 228 mmHg, the percent of inspired oxygen is the same as it is at sea level, where the atmospheric pressure is 760 mmHg.
