A person living at sea level has approximately 5 million red blood cells per cubic millimeter of blood. In comparison, a person living at 5400 meters has about 8 million red blood cells. Because of the high altitude
- a)UV light and increased red blood cell production
- b)People are pollution-free-breathing air, and more oxygen available
- c)People eat more nutritious food, so more red blood cells are formed
- d)Low O2 content in the atmosphere requires more red blood cells to absorb the O2 amount needed for survival.
Correct answer is option 'D'. Can you explain this answer?

A person living at sea level has approximately 5 million red blood cel...
Explanation:
Introduction:
The correct answer is option 'D' - Low O2 content in the atmosphere requires more red blood cells to absorb the O2 amount needed for survival. This is because living at high altitudes, such as 5400 meters, poses challenges to the human body due to the reduced oxygen availability.
Explanation:
1. Low Oxygen Content:
At higher altitudes, the concentration of oxygen in the atmosphere decreases. This means that each breath taken at high altitude contains less oxygen compared to sea level. As a result, the body must compensate for this lower oxygen content in order to meet its oxygen requirements for survival.
2. Oxygen Transport:
Oxygen is primarily transported in the blood by red blood cells, which contain a protein called hemoglobin. Hemoglobin binds to oxygen in the lungs and carries it to the body's tissues. Therefore, when the oxygen content is reduced, the body needs to increase the number of red blood cells to ensure an adequate supply of oxygen to the tissues.
3. Red Blood Cell Production:
The production of red blood cells is regulated by a hormone called erythropoietin (EPO), which is released by the kidneys in response to low oxygen levels. At high altitudes, the low oxygen content triggers an increase in EPO production, leading to an increase in red blood cell production in the bone marrow.
4. Increased Red Blood Cell Count:
As a result of increased red blood cell production, individuals living at high altitudes, such as 5400 meters, have a higher red blood cell count compared to those living at sea level. This increased red blood cell count helps to enhance the oxygen-carrying capacity of the blood, allowing the body to better meet its oxygen demands.
Conclusion:
Living at high altitudes with low oxygen content in the atmosphere requires the body to produce more red blood cells to compensate for the reduced oxygen availability. This adaptive response helps ensure that an adequate supply of oxygen reaches the body's tissues, allowing individuals to survive and function at high altitudes. Therefore, option 'D' is the correct answer.

Atmospheric oxygen is less and hence more RBCs are needed to absorb the required amount of oxygen to survive. At higher altitudes, the composition of air remains almost the same as at the sea level, but the density of the air gradually decreases. Number of red blood cells per unit volume is likely to be higher in a person living at high altitudes. This is in response to the air being less dense at high altitude. More number of red blood cells (more amount of hemoglobin) is needed to trap oxygen from the rarefied air having low pO2.
