    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.”

    Cannot get enough of these medical/biology videos! More histology videos would be great. Incredibly helpful as a student. I constantly crave different points of view or references. Don't know where I'd be today without Salman Khan!

    You've solved the audio issue, great! I think having two lectures can work, but I find it harder to maintain my concentration througout the video when the "interruptions" are this frequent. I think it would be a good idea to have Sal in the first few videoes in a guest lecturer playlist, but then let e.g. Dr. Prober or Dr. Connolly make the rest of the playlist on their own. This way, Sal doesn't always have to be there during recording, and will have more time to do other work. Great video btw!

    Great Video! I like where you are taking the Khan Academy. I personally look forward to seeing some videos on aeronautics eventually. Keep up the hard work, and excellent idea bringing in an expert in the field to help explain the details. I found the back and forth chat to be helpful.

    @igorkrupitsky this is Aperio Imagescope. It's actually a scanner with a microscope lens on the end. Files are about 3 gigabytes each and ".svs" format.
