How do we make blood clots? | Human anatomy and physiology | Health & Medicine | Khan Academy

[@brunorangel8088]

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.

[@fanvd]

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

[@farahshbeeb7954]

yup i agree

[@lydiahill-expertineradicat657]

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

[@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.

[@drharshilgpatel]

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

[@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

[@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

[@aminmawed8801]

god bless u for teaching it in a perfect way

[@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

[@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!

[@Amiinerz]

Best video I've seen on this topic thus far

[@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..

[@MushroomKing30]

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

[@ngochuyen8709]

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

[@cherrycherry7237]

Add more video about coagulation with intrnsic n extrinsic factor

[@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?

[@davidguerrero5640]

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

[@Jumboo364]

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

[@nadeerahiggs3217]

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

[@debasissahu5261]

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

[@matveisoykin4182]

Thanks for perfectly explaining this to me

[@mamyraelison9009]

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

[@sabbyful]

Khan Academy can I just get my MD from you?

[@raymondadomako5401]

Fantastic delivery

[@EleosAnim]

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

[@sebastiansebastian6485]

Nice vid, i will never see it again

[@earhaishasoriano4371]

Best presenter about this topic so far! :D

[@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?

[@Koalaslovesloths]

Lovely and solid explanation thank you!

[@bidyuthalder377]

nice explanation

[@ChiddyChiddy01]

thank you!! this was so helpful!

[@priscillapleasant3399]

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

This video really helped me

[@aneeshpandelu3442]

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

[@nouralsaeedi8161]

this is sooo helpful. thanks

[@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.

[@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).

[@emanzaareer1194]

Dose the fibronectin is the same of the fibrinogen??

[@madhulikagoel2192]

Through thrombin secreted by platelets. Converts fibrinogen into fibrin

[@smithsonchris20]

again thank you. great video.

[@richardsantacruz7129]

What is the final step in clot formation?

[@S78635]

sick vids man learnt so much

[@زينبقيسعَدَّاي]

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

[@Strawberry-cu6wr]

You are the best! teacher ever! :d

THANK YOU

[@daniellasinan1668]

thank you soo much

[@vincenttelfer4206]

cool, basically the endothelial cell is reconstructed?

[@samwilson3035]

Thank you! 👏🙌

[@ericbaxonn9878]

Did he mention anythn abt loose & stabilized fibrin meshworks?

[@doublecrosserthunder]

what software do you use?

[@loiscashner6567]

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

[@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

[@AlejoConejo-vb8ln]

Watch in x1.50 or 1.75

Stop commenting so much. You need to comment once.

[@Buchavka]

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

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