Neco 2025 Biology Question 16
Practice objective / multiple choice question 16 from the 2025 Neco Biology examination.
A person at rest has a heart rate of \(70\) bpm and a stroke volume of \(70\) mL. During moderate exercise the heart rate rises to \(130\) bpm and stroke volume to \(95\) mL. Muscles receive \(20\%\) of the cardiac output at rest and \(60\%\) during exercise. Each millilitre of blood carries \(0.2\) mL of O₂. Calculate the increase in oxygen delivered to the muscles (in mL O₂ min\(^{-1}\)) from rest to exercise.
