A level Biology Revision "The Cardiac Cycle"

You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at the cardiac cycle. I take you through the events taking place during the cardiac cycle, including atrial and ventricular systole and diastole as well as the roles of the atrioventricular and semilunar valves.

I progressed from a 4 3 in year 10 mocks to a 9 9 in My GCSE. All thanks to your videos, they were the only source of my revision. I am now studying Biology at Alevel :)

[@milanacs1916]

That’s the exact same for me I went from 33 to 88 in my GCSEs thanks to this guy

[@Oblivion.309]

You’re honestly a national hero

[@awesomepig99withpiggy30]

Absolute legend! Single-handedly carried my GCSE grades in all 3 sciences

[@tiramisu5494]

[@assassinod9462]

Hi sir, could you please tell me how much of the a-level content u have completed so far for biology and chemistry as I just started my a-levels and would love to use ur videos for my revision.

[@Freesciencelessons]

I've completed around 40% of both. I aim to have completed everything by the end of 2023.

[@shush1111]

[@zackbarnard2027]

Great video sir, just wondering whether the title is meant to be the other way round

[@Freesciencelessons]

Well spotted (and now corrected). Thank you for letting me know.

[@rionmuhaxheri150]

Are you planning on doing A-level Physics

[@JohnSmith-kn5xx]

I am honoured to be one of the first to watch this video

[@jazzie-noodle]

really help haha

[@learner0661]

Do these videos work for eduquas?

[@Freesciencelessons]

Yes they do.

[@ellal1067]

You’re an icon

[@studyaccount7677]

What would you say is the easiest exam board for a level chemistry and a level biology in terms of exam questions and content?

[@bellak1171]

In Edexcel its easier to score marks as there is slightly more content than AQA.

[@godgokuish4323]

​@bellak1171 Kinda false tbh edexcel isn't generous with marks in the slightest u can have a question that'd seem as a 6 marker be a 2 marker I did one on carbonhydrates and the amount of points I had to write for 2 marks was insane and I only got 1

[@tonyjones9442]

I watch these videos in middle age, I wonder are there any other middle age people who watch these videos for fun/interest?

[@Freesciencelessons]

As a middle-aged person myself, I'm happy to find that any middle-aged people are watching them. I hope you enjoy them.

[@tonyjones9442]

@@Freesciencelessons yes, i think we do. I think the quality of science education seems better than it was in Wales in the 90s. I was watching BBC bite size the other day and it was interesting although u could quite early see a political bias. Anyhow, thanks again.
(I got onto your videos as I was trying to get fit and loose fat and I found the triglycerides videos.)
