Final Answer:
The average rate of respiration for a normal adult ranges from 10 to 20 breaths per minute. Thus the correct option is b.
Step-by-step explanation:
Respiration rate refers to the number of breaths taken per minute, reflecting the exchange of oxygen and carbon dioxide in the lungs. For a healthy adult, the average respiration rate typically falls within the range of 10 to 20 breaths per minute. This range ensures efficient gas exchange to maintain adequate oxygen levels in the body and expel carbon dioxide. Factors such as age, health status, and activity levels can cause variations within this range, but the average rate remains around 10 to 20 breaths per minute for most adults at rest.
The respiratory rate is an essential physiological parameter indicating the efficiency of breathing and oxygenation. It's a vital sign often assessed in clinical settings to evaluate a person's respiratory health. A rate outside of the normal range can signal various health conditions or indicate the need for medical attention. For instance, a rate lower than 10 breaths per minute (bradypnea) or higher than 20 breaths per minute (tachypnea) could indicate underlying health issues, such as respiratory distress, infection, or metabolic disorders.
Maintaining an average respiration rate within the range of 10 to 20 breaths per minute is crucial for adequate oxygen supply to tissues and organs. This range allows for efficient gas exchange while accommodating variations based on individual factors. Monitoring respiration rate helps assess respiratory function and overall health, providing valuable information for medical professionals in diagnosing and managing various conditions related to breathing and oxygenation. Thus the correct option is b.
