Post-Video Quiz: 1. What are the functions of the arteries, capillaries and veins? (0:20) 2. What are the properties of the arteries, capillaries and veins? (0:42), (1:24), (2:26) 3. Define permeable (1:52) 4. Why do veins have valves? (2:56) 5. How should you calculate the rate of blood flow? (3:30)
Well, firstly arteries don't reduce their pressure they always have high pressure secondly capillaries have lower pressures and how they reduce the pressure is when the blood splits into different capillaries the blood pressure reduces. Think of it like this you have water flowing down a tube at the end of the tube the water would come off quite fast but now imagine that tube splits into smaller tubes and they end in the small place what would happen is water still comes but less water comes and it comes slower this is the same with capillaries they split up into smaller ones causing the blood pressure to decrease and slow down.
Arteries carry blood that's just been pumped by the heart around the body this means that that the blood is at high speed and high pressure however as the blood travels around the body it looses momentum and slows down
@@armstrongtixid6873 same . I'm in y8 and i want to revise in preparation for my GCSE. People on the student room and people i talk to in general say that i shouldn't worry about my GCSE cos they are 3 years away and i should enjoy the free time i have left. The only reason i want to revise is so when i start my GCSE course at my school i have time not to worry about Biology cos i'm so good at it and i can focus on my weaker subjects like English and RE and math's .
@@beyondtheordinary5550 Exactly. I do Maths, all 3 Sciences, and Languages in Y8 to GCSE Level, then I focus on English, Geography, History etc. and have a comfortable time at GCSE.
Blood vessels are 3 types. These vessels are filled with blood but works individually. Artery, Veins, Capillaries are those blood vessels. Arteries carries oxygenated blood and is red in color. It's thinner than veins. Veins are the blood vessels with wider boundaries, carries deoxygenated blood which is blue in color. Capillaries are the thin tubes also called vessels. It's the thinner wall among the blood vessels that even the food molecules and gas exchanges also take places.
Blood is not blue in color. The blood drawn from vein for blood test is red and it is from your vein. The blue color of vein is to do with iron in blood and quantum physics.
arteries are thick because the blood trasnported by it flows at high pressure. Hence,it is thick so that it can withstand it if not they will be damaged. VEins are not thick

an easy way to remember is that the artery can be remembered as out-tery (away from the heart) and the veins as ve-in (towards the heart)
clever
Thank you!!
oh smart
amazing dudee fabulous
Nice method
Super useful, my biology exam is tomorrow. Wish me luck!
Me too! goodluck!!
@@scarletchuter9283 It went so well i feel
Mine is tomorrow, pray for me! 🥲

@@Matt-xh7wq yes, thank you! it helps a lot :)
thank you but there are two 3's
@@ibrahimvardag8685 Thanks for telling me, I guess I was tired when I made the quiz
This used to be the topic I was worst at. But, now its one of my favourites. Thank you!
i have my biology igcse paper today and studying here as i dont know anything
@Dylan Lamond managed to get a C just by studying 1 day
An easy way to remember where the blood is being transported to in arteries is A for arteries and A for away. It helps me every time 😊😊😌😌
yep and: veIN - INto heart
@@xfreja for veins i do toVards the heart in a german accent
Or just remember the actual function
My bio exm is 2hrs later, wish me luck
Did you pass?
Wish u aol the best
This man right here is saving me. Thank you SO much!
The handwriting is so cute!
Thanks so much you are awesome ! I appreciate your effort.
Tysm i really needed this video tysm
Thank you so much for the clear and detailed explanation about the blood vessels ^^ keep up the great work :))
Thanks Strawb3rry, glad you enjoyed it 👍
Heyy, just wanted to pop in here and say that you helped me get a 94 for my previous exam, tysm!!
thanks sir I truly appreciate your videos. It was helpful :)
These videos are so useful and help me so much all the time, cognito could u pls make vids like this for computer science
thank you so much this really helped me understand :)
ur the one who makes this interesting for me
I was confused when my teacher took this u made it thank u㋛︎
Thankyou so much you save my exams
You're absolutely brilliant thank you
Definately more detailed than FreeScienceLessons for this video

really easy work
so helpful !
hi im confused but thanks
DioN I was crying 👁👄👁
Me too

It’s pretty easy to understand ngl
it's not that hard to understand
Hoping everyone gets the grades they want
Subhanallah thanks for these videos, much gratitude from me.
Really helpful. Thanks❤️
ty helped me alot !
Who has bio gcse tmrw
Me
Love the content! Keep up the great work buddy :)
im here from online class how do i tell my teacher i dont understand still
You don't understand because you don't want to understand. If you force yourself there is no positive outcome.
Thank you.
An easy way to remember artery is the A stands for Away
Accoirding to another video OUTery, VeIN
Thank you so much
online school pog
Educational... nice
For 3:43, that type of question would be in maths, which refer to the traingle method

I have a question how pressure reduces in capillaries and arteries
Well, firstly arteries don't reduce their pressure they always have high pressure secondly capillaries have lower pressures and how they reduce the pressure is when the blood splits into different capillaries the blood pressure reduces. Think of it like this you have water flowing down a tube at the end of the tube the water would come off quite fast but now imagine that tube splits into smaller tubes and they end in the small place what would happen is water still comes but less water comes and it comes slower this is the same with capillaries they split up into smaller ones causing the blood pressure to decrease and slow down.

would you be able to do alevel videos? you videos are amazing....
Thanks for the support - A level videos might be a while, just due to time constraints at the moment :)
@@Cognitoedu oh my gosh that would be so lovely!! hope you're doing okay atm!!
Yo what does it mean when veins contract ?
when veins carry blood back to the heart they contract to move so they can make their way back

what is smooth muscle ?
Isn't Vein are drawn in Red and Artery In Blue??
Opposite way around arteries red veins blue
Great!

what is up with this comment section? lmaoo

I am the only commenter on this video 🥴
i personally like both. you don't need to compare. they both work hard and have awesome videos.
wait but why vessels are thick?
arteries are thick because the blood trasnported by it flows at high pressure. Hence,it is thick so that it can withstand it if not they will be damaged. VEins are not thick
Poggies Moment !
Had to do this for yr7 science.
