Hemostasis | Advanced hematologic system physiology | Health & Medicine | Khan Academy

Hemostasis is the process which stops bleeding after an injury. Blood vessels are repaired by the creation of a platelet plug during primary hemostasis, and the platelet plug is further reinforced by the conversion of fibrin to fibrinogen during secondary hemostasis. Created by Gricelda Gomez.

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 wont go into detail" but thats what khan academy has always been about

[@Apratim98]

Check out mine for details included..

[@isaacrichardson1641]

It’s good for a short brief review when you are doing sports , holiday and toilet and so on. May I suggest you go to buy a textbook to details. Once you finished the video here, those video can help you understand the text book

[@isaacrichardson1641]

Hmm. Honestly.. unless you want to be a Docotor . In treatment level . Although those information(you need handy practice) are not enough but helpful

[@michaela4234]

Noo! First step to stop bleeding is vasoconstriction from vascular spasms - then platelet plug formation. This is not advanced at all and is skipping steps. :/ usually khan academy is a lot better than this.

[@julio97402]

I love Marry, thanks for the videos they were extremely helpful.

[@ThOutRider2]

Very very nicely explained. Thank you for making this video.

[@abdullahbasamh6210]

I don’t know why people are complaining about her not going into details, obviously there will/there is an another episode for those details, Very helpful video, thank you.

[@rmtascpi5936]

Thank you so much!

[@robertabso]

Thank you for this! You did a great job!

[@user-vw4yh6ld7n]

Thanks a lot

[@aidanjh7453]

It would be great to learn about hemostasis and not fun facts about blood vessels.

[@nicholekeller2737]

Even though this is a 6-year old comment, I'm sure you're fun at parties...

[@aidanjh7453]

@@nicholekeller2737 You too!

[@hyperduke26]

Thank you for a great and simple video.

[@louemt]

This doesn’t seem advanced at all. (Molecules and proteins, clotting factors .....) how about wills brand factor , thromboxane etc.... change title please

[@Apratim98]

Check out mine too for the same with details included..

[@Abominatrix650]

It's when you get to the pathways. Then it gets tough.

[@Ronkerboy]

im still stuck on 150000km... how, what where?

[@IVAN3000]

30 seconds worth of hemostasis in this 6 minute video

[@trusttrust9740]

this was really helpful. thank you

[@gabymeetsworld1034]

You did great :)

[@ztomczyk]

moral of this story: platelets plug, then fibrin...Where is the entire clotting cascade? how about fibrinolysis and endothelial repair? This might help with a high school anatomy class, but not the level Khan is known for...go into the details...

[@MrJingod]

Talk so slow! But still very helpful. thanks!

[@nperacc]

lol ya i watch it on 1.25x speed haha

[@sacredsponge161]

H-Everybody... wish you could talk

[@comedy0stuff]

You mean Mary likes to play football ?

[@reaznov]

sweetpotatogains exactly

[@biometalguy1]

Why isn't this video in the Khan Academy app?

[@Chickenwitz]

can't stand the breaks in her speech.

[@fdhlytl2665]

+Yvonne Reyes i sped up the video to 1.25 faster, that helps ahaha

[@ceeebs01]

+Aquilah Salman how did you speed up the video?!

[@nafisulislam4376]
