Question

9. Tidal volume in respiration is analogous to what measurement in cardiac physiology? A. Cardiac output C. Stroke volume B. Heart rate D. Systolic pressure​

Answer 1

Correct answer is: C. Stroke volume.

EXPLANATION:

• Cardiac output is ' volume of blood per minute ' or the amount of blood pumped by the heart per minute.
• CARDIAC OUTPUT= Stroke volume × Heart rate
• Tidal volume in respiration is equivalent to STROKE VOLUME in cardiac physiology.
• The number of times a heart beats in one minute is called the heart rate.
• Blood pressure during the contraction of heart is called as systolic pressure.
