Oxygen content | Human anatomy and physiology | Health & Medicine | Khan Academy

Learn how oxygen content (CaO2) is related to Hemoglobin concentration (Hb), oxygen saturation (SaO2), and the partial pressure of oxygen (PaO2). Rishi is a pediatric infectious disease physician and works at Khan Academy. Created by Rishi Desai.

Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

Very well done! Keep up the great teaching! I'm trying to learn about the lungs and lung function!

Helped a lot clearly explained thank you very much

[nathantjenkins]

does hematocrit percentage determine the oxygen carrying capacity? or is it the hemoglobin itself?

[boltingvenom]

Does oxygen bound hemoglobin contribute to PaO2 in arterial blood?
