Ten years ago I qualified as a doc. I now work as an anaesthetist. In that time no one has explained the process as succinctly as you have. Thank you, you have simplified many daunting topics and your videos provide short, bite size revision points for post graduate exams.
Keep doing your thing !

[@jakesouth2]

Your videos are so clear and very well organized. After studying the subjects in my text, watching your videos solidifies and organizes the information in my head, and your graphics make it both entertaining and very easy to follow.

If you cut deep enough is there a point where the damage done is not repairable, For example deep enough that tendons is cut completely.

[@Huntho21]

You literally complete my PBL each week. Thank you su much for doing these videos.

[@beca1973]

I am an MLT going for my MT. I must say, these make a wonderful refresher, furthermore, The way you explain it and the visuals (as you know must of us are visual learners) make it so much more easier to comprehend. Thank you so very much! If you need more sharpies, let me know. Fantastic job!

We should all pay our tuition fee to u!

[@talkwithberryl7288]

you are dam right my friend, i wish he was my teacher such an excellent job he does all the time

[@sycamore0765]

TBH, I got 50/50 in my SGD(Student Group Discussion) in my AnaPhy class about the video you posted about Bone Fractures and Bone Repair. THANK YOU SO MUCH

[@onlinestudent-ht8sc]

this has made such a confusing and complex process into a very understandable lesson in 10 minutes, thank you very much. the drawings and layout are incredible

[@ajboswell]

Video proved really useful for my dissertation work related to platelet coagulation. I often watched this to ensure I remembered the functions of all the agonists involved. Keep up the work buddy, great channel!

[@asifhamid9676]

Ultimate lecture sir.
You are explaining n writing everything in easiest possible way.

[@jiminshighnote]

I've watched 2 videos and read from 2 books about this topic but I like your video the best. It is the clearest and most organised. It's easier to understand. Thank you so much!

[@roofarrow32]

Awesome!! Thank you. You broke down that process in a simple, easy to understand process! Appreciate it.

Thumbs up Ormando❤

[@pdc293]

Seriously, I was a little skeptical about watching this video at first because there are not that many views on it, but it is exceptional!

[@DavidL999]

Thanks, I always watch a ton of your videos when my exams are close, they always help!

[@Aaron_Orion]

You're a life savior! Who would know hematology is so fun yet so complex

[@amixaex]

THANK YOU for existing and making these videos !! They're freaking amazing and to the point unlike other videos that go on and on for ages !! my life seems so much easier now hahaha !! PLS KEEP MAKING VIDEOS !!

Whaou ! BRAVO !!!
(From a French Anesthesiologist Resident)

[@carissapurabaya9893]

Pembuluh darah yang mengalami kerusakan akan mengalami proses blood clotting dengan mekanisme:
1. Vasospasm/Vasoconstriction
(vasodilatasi terjadi bila non-injury cell)
Otot polos pada pembuluh darah akan terkonstriksi untuk mengurangi aliran darah. Signalling vasokinstriksi dilakukan oleh :
- Cells around area sends signalls
- Nerve reflex
- Myogenic Spasm
2. Platelet Plug Formation (platetet membentuk temporary plug untuk menghentikan pendarahan). Dilakukan dengan 4 cara :
- Plug Adhession
Von Williebrand Factors mengarahkan platelet/trombosit untuk menempel pada sel yang mengalami luka, platelet akan menempel pada daerah luka tersebut
- Platelet Release Reaction
Platelet mengeluarkan adenosin bifosfat (untuk menarik platelet lain) & serotonin protrombin A2 (meningkatkan Vasospasm & menarik platelet lain)
- Agregasi Platelet
Pengumpulan platelet pada area luka sehingga membentuk platelet plug formation
- Plug Formation
Penutupan daerah luka oleh platelet sehingga menghentikan pendarahan
3. Coagulation, berfungsi untuk memperkuat plug yang dibentuk platelet
- Intrinsic & Extrensic Pathway (clotting factors)  Protrombinase (aktivasi protrombin) yang berperan sebagai ‘lem’ untuk memperkuat plug
- Protrombinase dibantu dengan Ca2+ mengkatalasis :
Protrombin (inaktif) -> Trombin (aktif)
- Trombin dan Ca2+ menjadi enzim dalam perubahan :
Fibrinogen (soluble) -> Fibrin (insoluble)
Benang-benang fibrin akan menempel di seluruh yang kemudian menutup luka tersebut.
Thanks!

After searching many videos, I found this helpful

[@jnubkk]

You make everything *click* for me! Thank you for your contributions to students trying to understand how it all fits together! Keep it up, I'll gladly donate as soon as I graduate and find a job :)

Just want to say your videos are awesome and really helping me with my degree!

[@dr.leelaram]

Your explanation is outstanding Sir❤❤

[@emmapaulus99]

this was so helpful in bringing all the steps together in a cohesive manner...thank you!!

[@TropicalChris]

Great video, thanks! Could you possibly do one specifically on the coagulation factors (I thru XII) while explaining them? That would be a great addition to this :)

[@talkwithberryl7288]

wooow i luv your videos, pls dont stop making good videos you have no idea how much you help students like myself.

I love your drawing. It is visual which enhances my learning of the concept. I wished my professors can learn from you, this way is more interactive and appealing which helped me focus at listening throughout the video. Thank you!

[@jasonmyer3615]

Beautiful and easy to understand presentation... love ur way of explanation.

[@lisagonzalez2902]

This is extremely, so incredibly good. I can't even describe it. Thank you sooo much. A lot of information, but actually important stuff, and not soo much that it becomes overwhelming. Thanks!!

Terjadi pada pembuluh darah yang mengalami kerusakan. Berlangsung dalam 3 tahapan mekanisme
• Vasospasm atau disebut vasokonstriksi
Pada saat pembuluh darah mengalami kerusakan, maka eritrosit akan keluar dari pembuluh darah. Otot polos kemudian akan berusaha untuk mengurangi aliran darah dengan cara terkonstriksi. Vasokosntriksi ini terjadi karena proses signalling:
 Sel di sekitarnya mengirim sinyal
 Nerve reflex
 Myogenic spasm
• Platelet plug formation
Platelet membentuk temporary plug untuk menghentikan pendarahan. Terbagi atas 4 tahapan:
 Platelet adhession. Terdapat Von Williebrand Factors dalam darah, berfungsi untuk mengarahkan platelet agar menempel pada daerah sel yang mengalami luka, sehingga platelet menempel pada sel yang luka.
 Platelet release reaction. Platelet mengeluarkan adenosin bifosfat untuk menarik platelet lain ke daerah sel yang terluka serta mengeluarkan serotonin protrombin A2 untuk meningkatkan vasospasm dan agregrasi platelet.
 Agregasi platelet. Terjadi saat platelet dalam jumlah yang banyak berkumpul di daerah sel yang luka dan membentuk platelet plug formation.
 Plug formation. Daerah luka akan tertutupi oleh platelet untuk menghentikan pendarahan. Platelet plug formation akan menyebabkan aliran darah yang keluar menjadi semakin melambat. Namun penghentian pendarahan ini hanya bersifat sementara, sehingga perlu adanya mekanisme lanjutan.
• Coagulation
Pada proses ini dibutuhkan clotting factors, protrombin, dan fibrinogen yang terdapat di dalam darah. Koagulasi berfungsi untuk memberkuat platelet plug formation. Terdapat 3 tahapan mekanisme koagulasi yaitu:
 Intrinsic dan extrinsic pathway, dimana jalur keduanya menghasilkan protombinase berfungsi untuk mengaktivasi protrombin. Protrombin berperan untuk memperkuat platelet plug seperti sebuah “lem”.
 Protombinase dibantuk oleh Ca2+ yang berfungsi sebagai katalis yang akan merubah protrombin menjadi trombin.
 Trombin dengan Ca2+ akan mengaktifkan enzim untuk merubah fibrinogen menjadi fibrin. Benang-benang fibrin akan menempel di seluruh luka dan akhirnya menutup luka tersebut dengan stabil.
Setelah proses penutupan luka selesai, pembuluh darah tidak akan terjadi vasokonstriksi lagi dan aliran darah kembali normal.
Thank you for the explanation
