These videos are gold!!! You aren’t capable of imagining how helpful are you being to medical students like me, thanks for everything!! Also, we need more videos please come back soon hahahaha
Detailed & easier than some other videos. Very easy drawing to try & copy into my notebook, that was good. Some other videos I run out of space because I couldn't plan what was going to be drawn, it gets messy.
Sarah ...i like your videos..thankyou so much for these videos..i will be learn more about topics ..and lastly i will say ..plz make a another video or skeletal system or muscular system..please😎😊
Thank you for your lecture, it's very helpful. I have a question, if NaCl and H20 was reabsorbed 100%(65+25+5+5), how can it be excreted? sorry, if it sounds stupid...
100%is not reabsorbed . and there is nothing like exactly 65% or eactly 70% it depends on the amount. if u drink 2 liters of water at a time .. that will be excreted with in no time(all most 100% will be lost in a single urination) but if u sip 2 liters of water in and around 3-4 hours,that will be the different phenomenon ... the key is to maintain the balance in the blood .(this is done by counter current multiplier and exchange) . this is the same reason why we excrete yello urine some times and the transperent(like plain water)... so coming back to the question u asked . 5liters of blood of which 20%(1.2liters) would go to kidneys . of that 1.2 liters of blood 60% (720)will be plasma and 40% will be cellular component (which will not be filtered physiologically). about 65% will be absorbed in pct about 20-25%will be lost in loop of henly. the ascending part of loop of henly and early part of dct are absolutely water impermeable . so the rest 10 from late part of dct and collecting tubule(this is hormone mediated- ADH and aldosteron ) this 10 % is absolutely variable..this depends on the water available in that particular area and the solutes available is that area normally the key is to eleminate 590-600 mosml of solute from the body(biologic waste) for this purpose minimum of 0.5 liters of water is required as a medium ... so depending on the all above factors urine is excreted. or simple speaking its like preparing a curry .. adding salt and sugar as required ..we dont mesure salt exactly 15 /20 grams on a simple balance . this might be a bit lengthy,but i hope that it cleared ur doubt
Thank you - your pictures along with clear explanations are awesome.

Just found this! Wow. Thank you for such a clear and simple explanation for such a difficult topic.
This was a million times easier to understand than my physiology lecturer, I wish I had of found it earlier!
Great video-good pace, clear explanations -and the colors-love the clarity and colors!
Thank you, thank you and thank you. I just wasn't getting it during class but now I have a much better understanding.
Amazing work Sarah, keep it coming. Love your work, greetings from colombia!!
just in time for my exam, tks a lot verry usefull
Very helpful ،،keep going sarah
Could you please make more videos?? they're actually amazing!
it's just PERFECT ,,, Thanx a million Sarah it's so helpful

so awesome !!!!!!both the drawing and explanation
this was very helpful thank you sarah for sharing it
Thnks Dr. Sarah
thank you that was so easily digested. fab
What's the name of programme you are drawing with and you're seriously creative awesome explaining keep going
Sarah ...i like your videos..thankyou so much for these videos..i will be learn more about topics ..and lastly i will say ..plz make a another video or skeletal system or muscular system..please😎😊
Wow yh
Thank you so much 👍

100%is not reabsorbed . and there is nothing like exactly 65% or eactly 70% it depends on the amount.
if u drink 2 liters of water at a time .. that will be excreted with in no time(all most 100% will be lost in a single urination) but if u sip 2 liters of water in and around 3-4 hours,that will be the different phenomenon ... the key is to maintain the balance in the blood .(this is done by counter current multiplier and exchange) . this is the same reason why we excrete yello urine some times and the transperent(like plain water)...
so coming back to the question u asked . 5liters of blood of which 20%(1.2liters) would go to kidneys . of that 1.2 liters of blood 60% (720)will be plasma and 40% will be cellular component (which will not be filtered physiologically). about 65% will be absorbed in pct about 20-25%will be lost in loop of henly. the ascending part of loop of henly and early part of dct are absolutely water impermeable . so the rest 10 from late part of dct and collecting tubule(this is hormone mediated- ADH and aldosteron ) this 10 % is absolutely variable..this depends on the water available in that particular area and the solutes available is that area
normally the key is to eleminate 590-600 mosml of solute from the body(biologic waste) for this purpose minimum of 0.5 liters of water is required as a medium ... so depending on the all above factors urine is excreted.
or simple speaking its like preparing a curry .. adding salt and sugar as required ..we dont mesure salt exactly 15 /20 grams on a simple balance . this might be a bit lengthy,but i hope that it cleared ur doubt
Awesome so usefull !!!
Very helpful 💗💗💗🌸
thank you ❤
