Question

Breathing rate can be measured by

• A. Heartbeat count
• B. Amount of blood
• C. Haemoglobin count
• D. None of the above

Answer 1

Answer: (A)

Heartbeat count

The breathing rate can be measured by the heartbeat count. This is because the heart is connected to the lungs via the pulmonary artery. In a healthy person with the normal heartbeat, 60-100 per minute will have 12-20 breathes in a minute.

So the correct answer is 'Heartbeat count'.
