I don't think Dr.Campbell explained properly the blood return from the Alveoli back to the left side of the heart [ why ] there is a lot of sketching and gaseous percentages (ok) quick wild lines and he completely misses the graphic explanation- Dr. Campbell looks confused as to how to graphically explaining the physical function clearly of the gas exchange and how the oxygenated blood from the alveoli starts its journey back to the heart where are the veins (to the heart) If Dr. Campbell would kindly relook at his presentation perhaps he can clarify this confusing point.

Sir I can't understand what you are saying at 11.48 second

[@Campbellteaching]

If you have 100% saturations, the lungs must be working at 100% efficiency, you can't get more than 100%.

[@khadijahakinsanya7668]

1.A 2.B 3.D 4.D 5.C I hope all my answers are marked

[@dr.yuvarajanpalanisamy9805]

And what is the O2 saturation is in pulmonary artery 75% I heard in your videos of CVS system in both vein and artery O2 saturation is not much difference level not less than something 85 in vein and 95 in artery sir

[@Campbellteaching]

Systemic veins and pulmonary artery bold is normally about 75% saturated

[@dr.yuvarajanpalanisamy9805]

Ok sir thank you
