    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 am also a nursing student and not only did you help me get an A in microbiology and get into the program, but now you're helping me through the program! You are an amazing teacher and immensely talented. Just as Albert Einstein said "if you can't explain it simply, you don't understand it well enough." You explain everything so simply and I thank you so so much! You are great, Sal!

    I am a nursing student at Penn State. My professors a awesome and all, but we can only cover so much in one hour of lecture (per week) and then the lab is more doing things then listening. I am not sure why you post these videos or who you are, what you do... But you are definately a reliable resource that is helping me understand what I need to know to not only get good grades and pass my exams, but also you do it in such a way that I can remember it and apply it in my nursing. Thank you

    I'm a third year Microbiology student and Khan Academy has not only helped me pass but achieve my aim of coming first in every class for the past two years. Not only that, I'm a teacher's pet because I'm always the first to understand any new concept and am able to help my fellow classmates(they don't know my secret of course, feel guilty about it...sometimes). Anyway, thank you Mr.Khan and the entire Khan faculty.
