    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.”

    this was way too general for the scope of medical school but I'm grateful for the clarity.

    This can't be taught in a better way. After years of being exposed to the more detailed forms of cascades related to coagulation, I was still struggling with the main ideas and logic behind this process, and now its much clearer, thanks to you.

    There's something so satisfying about watching people draw on these videos - I don't how they do it so perfectly.
    Also everything is so well explained and colour coordinated, you even add in things like the reason behind the name of something.
    Thank you Khanacademy you have taught me so much 💛
    Wish people would complain a bit less it's obvious you can't cover everything in one video

  • @mikefixac
    @mikefixac Před rokem

    My understanding is that it's not older plaque that causes heart attacks, but newer clots. The cap breaks off, and the body retries to cap the cap causing a bigger clot, and restricting the flow of blood to the heart (If it happens in the coronary arteries).

    Im so confused now
    Blood clot is when a blood turned into solid or rbc is merging with each other
    While the other blood cloth is when a endothelial cell split up that forms a whole in blood vessel is also called as blood clot? Huhu plss help are they the same from the first one
