Function and Formation of TISSUE FLUID: A level Biology. How it is formed and reabsorbed

[@emilypinn4316]

I really struggled to understand this in class but your video explained it really clearly, thankyou so much!!

[@MissEstruchBiology]

Ahh that's great 🙌 So glad it'd helped you to understand as it can be a tricky topic to get your head around.

you explain so clearly , omg thank u

[@MissEstruchBiology]

So glad you think so, thank you! I hope the video has helped with your studies.

[@SkippiVarndenkof]

Thank you for this, I just needed a quick recap! For anyone else doing Edexcel board I have noticed the mark schemes like you to specify 'large *plasma* proteins', not just 'large proteins' for the mark.

Hi Miss Estruch, I'm currently 29, but planning to redo my A-levels as a Private AQA Candidate. I've always had a keen interest in Biology but never thought I was good enough to do it at A-level (I got a C in GCSE). I've been preparing using a Textbook from the 2015 Spec. Your videos are really helping to just give that little bit of Teacher input that I'll miss out on as a Private Student. Tissue fluid was one topic which gave me a little trouble in the book, but your outline has made me completely understand it. Thanks.

[@MissEstruchBiology]

hey 👋🏻 I love that you are following your dream. Shows it really possible to do it even through unconventional pathways. Tissue fluid can be a tough one. I'm so pleased it helped you!!!

[@JaeyunYD05]

I'm so glad your channel exists, I'm sitting my AS Paper 1 tomorrow and I'm now feeling so much better about it :)

[@MissEstruchBiology]

yay so pleased! Good luck!!

[@afshandavid5083]

Guys I,ve been founding this topic it seemed really hard but now literally all my doubts are cleared I,m so happy I,ve been struggling to clear by concepts but now it's all good😊 looking forward to watching her channel for more good understanding ❤

It’s as if you read my mind I was going to ask for this video! Thank you 😊

[@MissEstruchBiology]

That's lucky! I am guessing most Y12 students across the UK are up to the same point as mine, so hopefully, the lessons I am making each day/week for my classes to use at home will link well with what you are being set by the school. Keep safe and stay home!

[@emmaburroughs5345]

Miss Estruch that honestly sounds amazing thank you so much. I’m so worried about the amount of content I’m going to have to try to learn on my own and having someone to help and talk to like you is truly amazing. I’m so grateful 🥺❤️❤️❤️

[@rjames7212]

brilliant effort really enjoyed it but filtration is a non selective process so water potential will not change

[@MissEstruchBiology]

Hello, Glad you enjoyed it 😊 Water potential won't affect the filtration as its due to size of molecule and filter , but the filtration removing water and leaving large molecules behind does affect the water potential.

[@R.Imran18]

Thank you so much! Excellent explanation!!! 🥰

[@MissEstruchBiology]

So pleased it was helpful 😊

[@Teni-yh5xz]

Very well explained 👏🏾👏🏾

[@TheZackattack50]

Hi, Thanks for the video really helped. I just had a question about the ultrafiltration, if oxygen is forced out but red blood cells are not, what is the oxygen being carried in if that makes sense as there is no haemoglobin?

[@isabellagogerty893]

i could be wrong, but i think the oxygen molecules in the blood are probably extra, ie they are in the blood as well as the oxygen contained inside the red blood cells

[@GenixYT]

The oxygen comes from the red blood cells where oxyhaemoglobin dissociates due to the presence of HCO3- ions and these ions associate with haemoglobin to make haemoglobinic acid (refer back to transport of carbon dioxide) so there’s basically excess oxygen floating round in the bloodstream after diffusing out of red blood cells.

[@ameliamcdaid]

How and when does oxygen get from the haemoglobin in the erythrocytes to the plasma to be squeezed out the capillary? X

[@MissEstruchBiology]

This links to oxyhaemoglobin dissociation curves, have you watched my video on that? Oxygen unloads from haemoglobin and diffuses into the plasma if there is high CO2 or low O2.kzbin.info/www/bejne/mGOUlIhobcp7msU

What a great video!!! Do you do wjec? Alevel

[@valentinabianchi2837]

Hi. I have been doing some practice exam questions and in questions to do with why is there a 'build up/ accumulation' of tissue fluid (e.g. due to high blood pressure) the mark scheme says that the higher hydrostatic pressure inside the capillaries at the arteriole end increases the outward pressure from the arteriole end of the capillary and reduces the inward pressure at the venule end. I don't understand how the inward pressure at the venule end is reduced, could you please explain? Also, in these types of questions the mark scheme says aswell as more tissue fluid being formed, less fluid/ water returns/ is reabsorbed back into the capillary due to pressure/ lymphatic system cannot drain away all the excess fluid. How come less water is reabsorbed back into the capillary?

[@MissEstruchBiology]

I think its referring to the inward osmotic pressure, rather than hydrostatic pressure at the venue end. Because this osmotic pressure decreased, meaning the excess water is reabsorbed but then equilibrium is reached and there is no more net movement of water, you get a build up of liquid which then must enter the lymphatic system instead.

[@uwotm8770]

hi miss, if only the water from the tissue fluid is reabsorbed back into the capillaries, what about the rest of the tissue fluid that's not water?

[@MissEstruchBiology]

All the useful substances move into the cells, e.g oxygen and glucose. Waste, such as carbon dioxide and urea are dissolved in the water and move back into the capillary that way.

Hi miss this is probably a silly question but if water molecules are forced out and not retained how does the blood continue flowing?

[@momangal1543]

Nvm u answered it😂

[@MissEstruchBiology]

Glad you found the answer 😄

[@archiesutherland6127]

I thought the water potential stays the same through the whole thing, or is that oncotic pressure?

[@MissEstruchBiology]

The water pressure and oncotic pressure both change. Do you remember where to heard otherwise?

[@archiesutherland6127]

@@MissEstruchBiology for a level biology i heard the Oncotic pressure is always -3.3 but the hydrostatic pressure changes as it goes along the cappilaries

[@archiesutherland6127]

@@MissEstruchBiology but i'm not sure cause one of my books says oncontic pressure changes and the other doesn't

hmm might be an error in that book then.
