Oxygen in expired aira)10%b)16%c)19%d)4%Correct answer is option 'B'. Can you explain this answer?

Question

Answer

After a human breathes in Earth's air (roughly 78 percent nitrogen and 21 percent oxygen), he or she exhales a mixture of compounds similar to the air inhaled: 78 percent nitrogen, 16 percent oxygen, 0.09 percent argon, and four percent carbon dioxide.

Answer

Answer

Oxygen in Expired Air

The percentage of oxygen in the expired air is an important parameter to determine the respiratory efficiency of an individual. The normal oxygen concentration in the inspired air is around 21% and the amount of oxygen in the expired air is typically lower than this. The percentage of oxygen in the expired air can be affected by various factors such as the respiratory rate, the depth of breathing, and the metabolic rate of the individual.

Percentage of Oxygen in Expired Air

The percentage of oxygen in the expired air is typically around 16%. This means that the expired air contains only about 16% oxygen as compared to the 21% oxygen in the inspired air. The decrease in the percentage of oxygen in the expired air is due to the fact that the oxygen is being consumed by the body's metabolic processes.

Factors Affecting Oxygen Concentration in Expired Air

The concentration of oxygen in the expired air can be affected by various factors. These include:

Respiratory Rate: The respiratory rate is the number of breaths taken by an individual per minute. The higher the respiratory rate, the lower the concentration of oxygen in the expired air.

Depth of Breathing: The depth of breathing is the amount of air that an individual inhales and exhales with each breath. The deeper the breathing, the lower the concentration of oxygen in the expired air.

Metabolic Rate: The metabolic rate of an individual is the rate at which the body consumes oxygen. The higher the metabolic rate, the lower the concentration of oxygen in the expired air.

Conclusion

In conclusion, the percentage of oxygen in the expired air is typically around 16%. This percentage can be affected by various factors such as the respiratory rate, depth of breathing, and metabolic rate of the individual. It is important to monitor the oxygen concentration in the expired air to assess the respiratory efficiency of an individual.
