A Level Biology Revision "The Structure of the Human Heart"
Вставка
- Опубліковано 11 вер 2022
- You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, I take you through the structure of the human heart. First I explain to you the arrangement of the atria, ventricles, septum and atrioventricular valves. I then discuss the blood vessels leading in and out of the heart (the vena cava, the pulmonary artery, the aorta and the pulmonary vein) and how the blood flows through the heart.

@@Freesciencelessons missed you king
@@Freesciencelessons The greatest 🐐
he came back when the world needed him the most
I keep going to this channel even though I’m now 20 and I don’t do anything related to science. Still interesting to learn these stuff. Great work!
Same I’m glad I’m not the only one
Thank you from the bottom of my heart, Sir, for all your help throughout my GCSEs. Thanks to your guidance, I was able to get 9 for Chemistry, Biology and Physics.
LETS GO !
Sir, your timing couldn't have been better. I've got my exams in a month and a half and this is exactly what I needed.
You're a legend.
These videos are absolutely excellent. Bite sized pieces of information. Easily digested. I've learnt & held on to a lot of information. THANK YOU.
I forgot to comment this before. I completed GCSE and now moved on to the IB system. I got 9’s in all of my sciences in quite large part thanks to you. Keep being the saint of British system students mr freesciencelessons
you are the reason i passed my science GCSE last year. thank you so much
My God, I just got a presentation to do on heart structure on Thursday. Thank you soo much! This was really useful
This UA-cam channel is actually incredible
This is a very simple but complete explanation.
Aaah yess he’s back was stressing what I was gonna do without ur videos litrelly saved me in gcse
Thanks so much for helping me through my GCSEs
This will be so helpful this year
Think that this guy is carrying the whole of the nation at this point
Thank you so much for your videos, they're really helpful
ive literally just started a level biology and this is what i have to look forward too 🤣
Hey sir,
I will be doing my GSCE in a few years. My sister has recommended you, and all my teachers recommend you to. Your videos make learning in such a fun way! I will be doing biology with my teacher on the heart, but this could be some extra additional revision for me! Thank you for all the videos you have been uploading. I really look forward to watching them, and achieve (hopefully) a grade 9 (A**) In science.
Enjoy secondary skl while u can little man😭😭
@@sefatullahrahmani7481 Thanks man
@@pinkmangooooo same i’m in year 11 now revising for my first set of mocks and i’m sooo glad i wrote all my notes and flash cards in year 10 it’s saved me sm time
@@sefatullahrahmani7481 it’s horrible. I love working compared to that slog
This guy literally making me pass all my exams
i love the new intro! great video :)
thanks so much! Im didnt do a level bio, im an engineering student (biomedical engineering) but one of my modules is cardiac engineering and I need to know stuff about the heart and this was really helpful!! God bless :D
The goat is back
Love your vids man
Thank you so much. After obtaining a 9/9 at GCSE, I have decided to take Biology and Chemistry at A-Level alongside Maths + Economics. May I ask when will you finish all the videos of the content? I really appreciate these videos since they are quite useful for me relating to the spec, as well as understanding my learning.
So much nicely and easily learned. Thank you so much. 🥰🌹❤️
The king is back
Damn, forgot I subscribed. Gives nostalgia
Hey! I just want to say thank you for all your videos. They have helped me so much. Please say hi!
Hi and thanks for the comment.
I hope this guy stays alive for the rest of my life
Gcse pe content but you’re still a living goat
You Saved my Olevel grades got an A* in phy,chem,bio Hope the same will happen during Alevel
Woah thanks so helpful
Thank you so much, Sir!!!
Thank you for the comment. I'm glad that you found the video useful.
Thank u so much! U are amazing! :)
Omg he’s back when I needed him to start A Level biology. Slay
We missed you sir
It's so good to save u life saver senpaii
Amazing video! I was about to learn this tomorrow so you came at the right time :D
May I ask why you've chosen to make a video in-person instead of animated again? 🧐👍💙
Hi and thanks for the comment. After quite a lot of thinking about this, I realised that it's actually better for learning to have me in the videos rather than an animated version. And to be honest, I kind of miss being in them. So I'm now back in them.
@@Freesciencelessons 👍
@@Freesciencelessons he's back.
@@Freesciencelessons ily
I did this today and the practical on a lamb heart at school
Hi, when will you be starting the A level Physics Revision course? If you are going to start it.
Will you be doing a level physics
Sir
Please make video's on designing of investigation and experiments
Are your videos for all exam boards?
Also I would love to see some a level physics videos. I'm going to do all 3 of the sciences for a levels.
hes AQA i think
Yesssirrr
Sir, may I ask you if you will be explaining A2 biology or A2 chemistry?
Yes I'll be doing both.
will you always be doing in-person videos?
Yes I will from now on.
@@Freesciencelessons Our saviour is back :)
💪🙏
Hello sir am wondering does this also apply to eduqas?
Yes it does. Almost all of my videos apply to Eduqas.
