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.”

[@BaoTran-ls7oy]

Thank you for this video! For those who questioned why the word "Serum" was used, Fibrinogen is used for blood clot. Therefore, "serum" contains substances that are left after blood clot and is used for variety of diagnostic procedures.

[@UnbreakablePickaxe]

Really helped. Thank you

In terms of cholesterol, proteins and lipids. What is the difference between whole blood, plasma and serum ?

[@narminsalimova7334]

Thank u so much, great explanation. Many things I was confused with, are brilliant clear now. I wasn't able to grasp the concept of centrifugal process, though using that machine is the part of my new experiment, but now I know what I am doing

[@mohammadalihamidia7785]

[@arzooosoki7531]

[@DRASHIQURRAHMANBANGLADESHBIBAR]

Thanks

[@trionamcelligott5213]

When using a refractometer you use the serum and plasma tp levels to get the fibrinogen. But you said the serum doesnt contain fibrinogen? Is it that the tp from the plasma figure minus the serum represents the content which is fibrinogen?

[@AvieMare]

That was awesome!! And the icing on the cake for my OCD self was when you went back and fixed the "P" in plasma which had an unclosed loop. Haha. Peace, Avie

[@shahin2324]

[@nicholekeller2737]

You may also hear the term "Buffy Coat," which is the layer containing WBCs and platelets. Great video, by the way!

[@7r1n3santiago]

love all the videos from khan academy , keep posting :)

[@humeruslady1730]

Very helpful! I am the opposite I often stare at the needle as it goes in my arm and watch my bloods progress as it fills when I donate. Always remind me of a dark raspberry jam😊😄

[@niazkhan8588]

What program do you use?

[@taamardhwaj]

Video is still free and its 2020

[@1tightlinefishing631]

your not bad with a mouse thumbs up

[@Nicken0o0]

I think maybe he use some sort of graphic tablets..

[@joshpaul7232]

yup he's using some kinda pen pad...all the khan academy videos are like that

[@eltonolluri]

first of all thank you for the video, but I'd like to ask one more question: 1. Why there is no fibrinogen and clotting factors in serum, why do they take it out ?

[@munasaoudi7846]

your drawing is amazing 💜💜💜💜💜💜🙇

[@MikeViLLaZ]

Khan i have a request. For halloween could you do teratoma? how it's formed, what may cause it, what's REALLY inside and a break down on what the liquid portion is
