Primary hemostasis is balanced on the dynamic harmonious antagonism between the smooth endothelium (that prefers laminar blood flow) and thrombocytes (which favor clotting and thrombosis).
Platelets are called thrombocytes "cells of thrombus".
The smooth endothelium is squamous epithelium that lines the blood and lymphatic vessels from the inside.
When platelets roll over the smooth endothelium, nothing happens.
But, once there is an injured endothelium, platelets adhere, activate and aggregate to form a temporary platelet plug (primary hemostasis).
Then, the coagulation factors are stimulated "thanks to subendothelial collagen, tissue thromboplastin and platelet factor 3), coagulation cascade ensues until fibrinogen is converted into fibrin fibers trapping the RBCs and forming a stronger thrombus (secondary hemostasis).
After that, fibrinolysis occur (thanks to tissue plasminogen activator or tPA) to destroy the clot and restore function and flow.

Cutting the vessel longitudinally is worse causing no back-flow pressure to happen, making handing the bleeding worse!
This channel is too good
The way it explains 100+ pages in like 10mins is very handy
Thank you!
I can't believe How I managed to survive through med school without this channel.. this is so underrated
Thank you so much 😊
dude how did you manage to explain this more clearly in 10 minutes than my professor has in 3 weeks?!?! you're so good at explaining things and make them really easy to understand! I really appreciate what you do, keep it up!! :)

I’m so happy I found your channel. I recommended you to my classmates because our profs aren’t really helpful 😂
Thank you so much 😊
Professors and their PowerPoint 🤪
Test your knowledge by answering these FREE cases about platelets and bleeding disorders, written by me: goo.gl/APUimj
I'm addicted to your videos !
Please do more videos in Rheumatology
We really need them more than any other topics 😭
Thank you so much 😊 you're a lifesaver 💙
Thanks for your great comment...Wait for Rheumatology videos every Saturday 🤩
he good for hematology not interfair on his you need to join another one he will make you to easy sorry don not mind,
What do you mean? 🤔
@@MedicosisPerfectionalis Overstimulated Broca’s area
جااامد يا ميديكوزس، انا شخصيا اتعلمت منك الكثير، بارك الله بك وفيك-
Thanks, 👍
The answer of the question is (B) okay ,and that's why? Our blood vessel's smooth muscles are in the shape of circle so if we cut longitudinally we cut the circle of the muscle so it can't be able to contract in a good way.....I hope I am true🙂🙂
Going through ur video to teach my son thaks boy u r doing a great job
i am pulling an all nghter today !! this is a real breakthrough! your videoss maynnnn
Thanks 😊
I am so happy 😃
Medical science explains at a regular level. WELL DONE.
Thank you 😊

Thank you so much 😊
Can you please help me by sharing?

hahaha same xD
im totally stealing this, this guy is the smartest, coolest, funniest guy ever !!!!
Thank you 🙏
Thanks for the great explanations!!! Love your videos
Thank you 🙏
A is worse bcz vasoconstriction wont be useful, but in B it makes the endothelial cells closer i think
thanks for the video! amazing as usual
Thankyou for the minute details
You’re very welcome 😊
Am a bds student it is helpful for me though... Thank you ur videos makes me understand the topic very well.... Thnx😊
My pleasure 😇
You are my hero 💜💜💜💜 love u and thank u
And i think cutting the vessel longitudinally is worse based on my current knowledge on this topic
You’re absolutely correct 👍👍
@@MedicosisPerfectionalis is it because it doesn't have the back pressure?
@@collectingstars1 i think it's because the area of the injury is big enough than the vertical one
I am so pleased to found your channel,,making medicine fun caught my attention 😂😂
I'm so glad!
Would you please help me by sharing?
@@MedicosisPerfectionalis I already did that 🤩
Thank you so much Sir, everything was well explained!!
My pleasure 😇
The transverse cut is more likely to result in cutting other structures like tendons and nerves. this is the answer provided by google about wrist wounds here the question is not about tendons and nerves it's about the vessels so longitudinal cut is a real pain in the butt because first technically it's always difficult to deal with (I won't speak here about stitching techniques) BUT even if it's perfectly done in case of a longitudinal cut there 's always a higher risk of thrombosis because of the narrowing (after stitching) of the lumen of the vessel; on the other hand transverse cuts are easier to deal with
Answer is B.and thank you very much 😍
Love your channel! I send your videos to my hematology classmates all the time
Very good explanation 🌷🌷🌷
Thank you so much 😊
I shall subscribe and I shall do it now!!
What a magnificent display of informations you did there young man!!
Keep the good job!!
Srsly dude I have an exam and you just saved both my gluteus maximuses 🖒
Haha 😂

Thank you very much great videos 👍🏻
You're very welcome 😊
You are the best
You're awesome ❤️❤️
longitudinal cutting of the blood vessel is more dangerous because there is no backstopping endothelium and there is no back pressure. so the chances of you bleeding is more
Thank you so much sir 🙏🏼
You’re very welcome 😊
Can you please help me by sharing?
Medicosis Perfectionalis sure !
Please. Can you tell me .What is a clot ?
You’re so funny i like your videos please do more
I sure will:)
You are great, I wish that you can talk a little slow for one person, that is me. I am too slow to catch your speed.
Thank you for your honest feedback!
Thanks for the amazing video... Full of knowledge and laughter.... "why induce vasoconstriction, are you an idiot? To reduce blood loss" 😂
🤪😁😅
Thankkk you 🌸🌸🌸
My pleasure 😇
Thank you so much....

i think its the longitudinal blessure
True!
Longitudinal cutting of vessel
Why more water in ICF? I need answer this question
because you’re not a sponge...When I shake your hands, you don’t ooze water.
@@MedicosisPerfectionalis thank you very much
@@MedicosisPerfectionalis best answer ever
@@mohamedabdullahiazhary5794 the cytoplasm within the cells is mostly water and we are almost completely formed of cells
My pleasure 😇
Longitudinal cut is worse?
Why?
.
@@MedicosisPerfectionalis Because you don't have the back pressure from the blood! ...is that right?
Also, really wanted to thank you for making these videos, especially the leukaemia ones finally understood concepts haven't gotten in years
You’re very welcome 😊
Nice good information and presentation but very fast talking
Fair enough!
Thanks 🙏
Is it worse to have a transverse cut? Because it is perpendicular to the lines of something, I forgot ,,, anyways you end up with a scar ?
Tension lines...Is it?
Please CNS 😭
How you are amazing and fantastic to that extent 🤔🤔
Thank you 😊

@@MedicosisPerfectionalis cuz there's no back pressure ?\
Longitudinal cut is worse.

Funny lecture 😂
Thanks 🙏
Longitudinal cut is worse
Why?
on second thought the deeper the cut the longer healing.. longitudinal.. Longer longitudinal.. yes wait no
What am I doing with my life😂😂
