sorry to be that person, but there is a mistake at 29:24 - the SAN is located in the wall of the right atrium and similarly the AVN is located at the top of the septum inbetween the ventricles, not in the atria, otherwise this has been a good video so far, thank you!!

[@aeryoakton2651]

[@MissEstruchBiology]

You're welcome!

[@sofiaa1945]

has this included language used in the spec and mark schemes ?

[@bottykid9522]

Thank you so much for these videos!! Do they cover all the spec content or is it just an overview? Xx

[@MissEstruchBiology]

Covers all the spec content! Not maths or practicals though

[@Charlotte-pd2wl]

@@MissEstruchBiology Will you do a maths video and the practicals preferably if you have limited time, please

[@HelloKnow-sb7cm]

Lifesaver!!!!

[@MissEstruchBiology]

😁😁😁

[@klargeworden]

thank you so much for these videos! are you planning on releasing a video about predicted topics for the upcoming ocr papers? x

[@MissEstruchBiology]

Hey so pleased it's helpful!
No, I won't be doing predictions as there's no advanced information this year.

[@ellieheheh7519]

Thank you so much!! Sorry to be that person but at 5:19 , i thought bronchioles dont have cartilage?

[@insanegamer2886]

Hi, on the blood vessel table section for arteries you do not state about the tunica adventitia/externa, tunica media and tunica intima which are the three layers which make up the artery walls. Do we not need to know this as this is what is on savemyexams revision notes for OCR. Thanks!

[@insanegamer2886]

On savemyexams there seems to be a lot more detail compared to the slides in the video. Is this because your slides are more raw & straight to the point?

[@zizi8539]

could you do a whole ocr syllabus video x i did aqa last year and loved your video

[@MissEstruchBiology]

Hey, entire paper 1/2/3 videos are coming over the next few weeks!

[@charlesmosoeunyane1188]

Hope I enjoy😊😅

[@MissEstruchBiology]

I hope you do too 😊

[@charlesmosoeunyane1188]

Really?:/

[@matildaforan7390]

aren't hydrogen carbonate ions HCO3 not HCO?

[@user-lh2jr2dv2o]

On the slide at time 5:37 there is a little mistake as the bronchiole do not have cartilage support, other than that it looks like a great video tutorial :)

[@pingooice6760]

Larger bronchioles do contain cartilage whereas the smaller bronchioles do not.

[@user-ex9dj9et1g]

The ocr flash cards you’ve made are they spec specific? Or just overview

[@MissEstruchBiology]

They match the specification exactly

[@philippaboosey3687]

got my mock tomorrow and just realised I know NOTHING about plant transport... hopefully this helps

[@MissEstruchBiology]

Good luck!!

[@shumaiya4048]

does this also apply for the WJEC exam board

[@MissEstruchBiology]

There are some overlaps, but it's not an exact fit

[@sabirsdevv6806]

46:49 water of movement up the xylem lol

[@MissEstruchBiology]

😂

[@pybrandon]

[@MissEstruchBiology]
