Current Question (ID: 14309)

Question:

On an average, a healthy human breathes _____ times/minute.

Options:

1. 70-72
2. 20-25
3. 12-16
4. 120-80

Solution:

On an average, a healthy human breathes 12-16 times per minute. This is also known as the respiratory rate or breathing rate. The respiratory rate can vary depending on factors such as age, health status, and activity level. For example, infants and young children have a higher respiratory rate compared to adults. During physical activity or exercise, the respiratory rate may increase to meet the increased oxygen demand of the body. Conversely, during sleep or relaxation, the respiratory rate may decrease. A respiratory rate that is consistently higher or lower than the normal range may indicate an underlying health condition and should be evaluated by a healthcare professional.
