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.”

one word that could sum this whole thing up: BEAUTIFUL! beautifully delivered! Thank you!

[@mrkekman9526]

I just want to say a massive thankyou, Your videos are pulling me through my Med degree at the moment. Well done and keep it up.

[@lydiahill-expertineradicat657]

You have a very calming voice and I love the way you explain things. Thank you.

[@fanvd]

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

[@farahshbeeb7954]

yup i agree

[@Jumboo364]

THANK YOU!!! This made the last week of coagulation lecture so much more understandable!

[@michalmandelik3374]

BROTIP: Play it at 1,25 speed ;)

[@namirashaikh9012]

So helpful!!!!!

[@matveisoykin4182]

I like to play it at 2x speed

[@shivamsingh7389]

@@matveisoykin4182 that is so not possible i mean even if you were just brushing through the chapter you can by max go till 1.5... that is what i used. And i have done this chapter already to a deeper level, i was just brushing through it.

[@shivamsingh7389]

@@matveisoykin4182 Btw your youtube videos are really cool!!

[@zhori50]

1.75 is good tho

[@amirrezafahimi6579]

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.

[@foodandmoorehappiness]

This by far the best, most clear, and most helpful video I have seen on this subject - perhaps on any physiology subject I have seen. Thank you!

[@samuelchris9295]

You just spoke about platelets

[@sanpopnoobear2113]

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

[@drharshilgpatel]

Simplistic and excellent approach. Just revised concept read 8 year ago.

[@aminmawed8801]

god bless u for teaching it in a perfect way

[@Koalaslovesloths]

Lovely and solid explanation thank you!

[@Amiinerz]

Best video I've seen on this topic thus far

[@cherrycherry7237]

Add more video about coagulation with intrnsic n extrinsic factor

[@ChiddyChiddy01]

thank you!! this was so helpful!

[@earhaishasoriano4371]

Best presenter about this topic so far! :D

[@annaquesse2063]

Very interesting. I loved the drawings he used to describe the clotting mechanism. 5/5

[@harpreetsehgal5565]

Thankyou and god bless u in explaining this concept very clear..

[@davidguerrero5640]

I expected more sofisticated explanation, but you define the basics incredible easy, awesome, really genius

[@nadeerahiggs3217]

Beautiful Video!!!!!!!! I have a great understanding...A better understanding.. I love how you put your videos together

[@ngochuyen8709]

thanks you ! This video makes it easier for me to understand coagulation !

[@sabbyful]

Khan Academy can I just get my MD from you?

[@kerrybiery6360]

Wonderful presentation of a very complex system. The hematologists of the world can go much deeper, of course, but targeted towards an entry-level allied health student, your presentation is right on the money! And the drawings are great!

[@marimacdyer3148]

Super helpful! Thank you!

[@LufinaNF]

Thank you so much for this video. It's simple and easy to understand! Is it possible if you can make a video and explain how the venom (like from snakes) prefends our blood from clotting?

[@TheCrazyMango82]

You skipped thromboplastin and prothrombin and just went straight to thrombin. Which sucks because that's the part I wanted to know about

[@lifetorch1992]

+TheCrazyMango82 watch the clotting 2 video. i think this was meant to be more of an introducton to the topic

[@shivamsingh7389]

You already know it don''t you?

[@nouralsaeedi8161]

this is sooo helpful. thanks

[@matveisoykin4182]

Thanks for perfectly explaining this to me

[@sourichitsazzadeh2629]

This video really helped me

[@S78635]

sick vids man learnt so much

[@MushroomKing30]

Just a teeny tiny error: that's a longitudinal section, not a cross section But overall nice job :D

[@smithsonchris20]

again thank you. great video.

[@raymondadomako5401]

Fantastic delivery

[@Strawberry-cu6wr]

You are the best! teacher ever! :d

[@mamyraelison9009]

Very practical you see more clearly thé clinical évents of bleeding and Blois clotting

[@EleosAnim]

For a video that has 400k views i'm surprise it only has 80 comments

[@samwilson3035]

Thank you! 👏🙌

[@priscillapleasant3399]

Thank you for your information I had now ideal that's how the blood works. So thank you.

[@debasissahu5261]

This man is not Sal. But still he is a good teacher. Thank you a lot.

[@Courtney.Marie.K]

THANK YOU

[@daniellasinan1668]

thank you soo much

[@sebastiansebastian6485]

Nice vid, i will never see it again

[@caseycjb121]

Epic!

[@bidyuthalder377]

nice explanation

[@grandfather8661]

I was just reading Michael Denton, the I.D. proponent, on the ennucleate red blood cell, which he says is a defining homolog of class mammalia and was the topic of his doctoral thesis.

[@user-ln5xl6vo6z]

This video is ammmmmmmmmazing 😍😍😍 I wish if you can put the Arabic language with the captions of your videos ☹️💔

[@madhulikagoel2192]

Through thrombin secreted by platelets. Converts fibrinogen into fibrin

[@mikefixac]

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).

[@cellfish_me925]

Great:)

[@ericbaxonn9878]

Did he mention anythn abt loose & stabilized fibrin meshworks?

[@richardsantacruz7129]

What is the final step in clot formation?

[@aneeshpandelu3442]

Fibrinogen is from liver Fibrogen stabilizing factor - factor XII helps in cascade

[@doublecrosserthunder]

what software do you use?

[@vincenttelfer4206]

cool, basically the endothelial cell is reconstructed?

[@jaycoolswagger8780]

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

[@emanzaareer1194]

Dose the fibronectin is the same of the fibrinogen??

[@aceventura3935]

Wow amazing what Jesus can design ! So incredible !!!

[@rutvikrana512]

nice!! But So slow.........

rutvik rana true actually its so slow man

How do we keep blood clots from moving thru our veins, I’m having clots all the time

Pls we want arabic subtitles

[@thunderrain1717]

Whats his name?

[@AlejoConejo-vb8ln]

Watch in x1.50 or 1.75

i like it!

Man I wish these were shorter videos

Or you can just say clotting factors that are 13 of them lol

Stop commenting so much. You need to comment once.

[@paulhetherington3854]

Why not, explain blind spots-- surgery aspect? Because; you didn't study!

Beautiful lecture. But its not evolution that created us, It's God Almighty (The God of Abraham, Isaac and Jacob). Stop the ignorance!!
