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.”

    I'm in a healthcare professional grad school. This video was linked as part of our "prior to class" material. This should have been a "prior to graduating high school" material. so much covered in such a little amount of time that is easily listenable and easy to grasp. I listened on 1.5 speed and realized I needed to slow it down to fully grasp. Thank you again for amazing content. Y'all rock.

    HERBAL CURE IS THE BEST REMEDY FOR (HSV1&2)  I was a victim of herpes virus and i got cured by  Dr Osas  Herbal treatment is a 100% guarantee for HSV cure, the reason why most people are finding it difficult to cure HSV 1&2 is because they believe in medical reports, drugs and medical treatments which are not helpful to cure HSV and haven't proved any sign of helping. Natural roots/herbs are the best remedy which can easily eradicate herpes forever. I never believed it until I was helped and cured of my 2 years genital herpes with natural herbal medicines from Dr Osas Where other medical prescribed drugs and treatments failed, Dr Osas natural herbs helped save me from Genital herpes permanently and I am so grateful for this. You can also get help from Dr Osas on his email; Or WhatsApp/Call +2349154653305
