Neco 2021 Biology Question 46
Practice objective / multiple choice question 46 from the 2021 Neco Biology examination.
In the labelled diagram of the human heart, a patent foramen ovale (PFO) is shown connecting the left atrium (LA) to the right atrium (RA). If the left ventricle ejects a stroke volume of \(70\ \text{mL}\) per beat and the heart beats at \(75\ \text{beats min}^{-1}\), and \(5\%\) of the left‑ventricular output is diverted through the PFO back to the right atrium, calculate the net volume of oxygenated blood that reaches the systemic circulation each minute.
