U too
U too thanks
u tooooo

Why thank you I have mine today
I teach biology to non native English students. Your clear, measured language an diagrams help them.
Thanks Liz - really glad they work in that setting 😊
I swear everybody I know tried to make me understand this but no one could you only took 6 minutes and I memorise every word and understand it too.
Thank cognito thank you very much!
Ah that's awesome to hear, thank you so much Mostafa 🤩

whats 11? they are all inhibited
@@abdinassor805 FSH Increases Oestrogen, but as oestrogen increases it inhibits FSH. Oestrogen increases LH
Thank you sooooooooo much

@@MudNic1 literally walking to school rn to take paper 2 😮💨
@@surullop7122 how was it mines tdy
It took us guys one months of one hour classes twice a week to finish this chapter in class! But, i don't believe what superpower this guy has that he finishes these topics in 5 minutes!
omg ty this so useful all other videos were either confusing or just straight up worng
Thank You very understandable and easy to follow vid I found menstruation the hardest when learning
I did great in the theory paper . I will have multi choice tomorrow . Thx for everything
Need an i love cognition shirt rn ! So good
amazing video, so informational. Maybe you could specify, in future videos, which information is necessary for each board. For example some things may not be needed for edexcel but for aqa. But still very good :)
Thanks Karan we'll keep that in mind for the future 👍

@@HA-wd2pu good times i miss those
Amazing absolute masterpiece I am very proud to have you on the internet and in my life. You are very inspiring to others and I will remember you when I write my exams by Adiplayzfn
Thank you
is this for the edexcel specifiaction or does it not matter?
Wow thank you💓💓🤗
My biology teacher always send the students here to watch his videos
what do you mean by high tier do you mean tripple science or just normal gcse science because i have been doing all except high tier by the way your videos are so helpful thank you
Higher tear GCSE biolagy is for students aiming for grade 4-9 it provides flexibility aswell chang-able and planeble exams + practicals hope that explains it :)
Thanks for the video!
I'm a bit confused about why Oestrogen inhibits FHS in the first place?
because if it doesnt, then FSH will further stimulate more eggs cells to be released, so more sperms and egg cells will form more than one zygotes. Thats why when FSH is failed to be inhibited, people have twins and triplets. But usually, the human body is made to produce only one zygote. Hope this helps
Hi... what happens to oestrogen when progesterone rises?
this was really helpful!! thank you so much!
You're so welcome!
You got something rong in video the bleeding normal stays for 5 days not 4 depending on body
It actually ranges from 2-7 days
It’s not specifically 4 or 5 days
rong?
this helped so much
however there's no mention of what causes progesterone level to increase and decrease in the interaction section? any tips
An increase of luteinizing hormones triggers the corpus luteum to produce progesterone, however if an egg still hasn’t been fertilised by a sperm, the corpus luteum drops the levels of progesterone, therefore causing menstruation (idk if it’s all correct tho)
@@ena-1717 oh that makes sense thanks :)
Last minute revision, it's 12 44 and I haven't learned this yet
very helpful :)
I. Loved. This. Video
Sir! I have a question about progesterone. I do not understand the last part where progesterone inhibits both LH and FSH
Progesterone is basically the hormone that says 'oh hell no, LH and FSH. You ain't gonna be making more eggs any time soon!' In other words, Progesterone stops FSH and LH from affecting the menstrual cycle further until the next cycle comes in.
@@hamzie1010 thank youuu!!
