- Osmolality, Osmolarity, and Tonicity.
Osmosis is a special type of simple diffusion (specifically for water). Osmosis is the movement of water from high concentration of water (low concentration of solute) into low concentration of water (high concentration of solute).

I just love listening to you talk. The material sticks so well in my head! ;)
Awesome 👏
Thank you so much 😊
been searching answers to my questions about these minute details.. got so many basics cleared... a big thank u. ❤️
My pleasure 😇
Great lessons! And funny! That's what makes it more engaging. Thanks a bunch!
My pleasure!
This will be perfect when its time for sem 1 revision
Abhinav Singh what are you studying? Just curious
@@army4life954 year 1 BMedSci/MD.
very helpful, and engaging - you are an amazing teacher!
Thank you for making medicine fun....a big big fan
Thank you 😊
You mentioned ethanol talking about effective osmoles. Is it an effective or ineffective osmole?
Hello! Our teacher , always fascinated by the way you explain your lessons , thank you
I have a question please ,i m preparing my exam about renal physiology ,i m searching for questions MCQ about that item ,can you give me a website for Free to evaluate myself . keep going your nice work.
I don’t know about websites!
I know some books:
Guyton physiology review (the entire book is questions and answers)...Renal chapter.
Ganong review...Renal chapter.
Love the way to teach you explain you speak
Everything 💞
Thank you 😊
you never disappoint me
thank you best teacher
My pleasure 😇
haha love the way you explain this! love the way you talk.
Thank you!
Thank you so much!. As a first year medical student i find his extremely helpful.
My pleasure!
If you heat 100 mLs of water the volume (osmolarity) will expand but the weight (osmolality) will not. The lightbulb just went on! 💡 (PS: After university, I lived in Edinburgh -- love Scotland, my ancestral homeland.)
Thank you so much for watching!
you are the best
THANK YOU SIR
1:35 my fav part
You’re welcome!
Thank u for making this easy and enjoyable
Love listening to you teach 🥰🙏🏾
Thank you so much!
I am honored!
Thank you so much but I just have a question the Na+ passes through the channels of the plasma membrane as it is a small ion passing with water and also durnig the active transport through the Na, K pump so how it is an effective osmole?
Dear sir your speed should be little bit slow, thank you
Thank you for your honest feedback!
Hi, Thank you so much for your explanation!
I am preparing for the CSMLS exam. Do you know any source of questions that can help me!
Nice video and good channel and teacher 😊👍
Thanks a million!
🙏
Can you explain what is osmoregularity ?
legit best for quick review
6:28 exercise Z says 500 cc
it means 1/2 a liter if i'm correct?
👌👌👌very good
Very nice video :) I have just one question i not really get. In the nephron we have urea transporters (for example in the end of the collecting duct). For transport of urea back in the system right?
And how we get an urea concentration in the nephron when its always moves through cells?
Urea back-diffusion occurs from the nephron (tubule) to the renal medullary interstitium…This urea will help pull water out of the tubules making the urine more concentrated.
WE DON'T LET PHYSIO PROFESSOR NEAR PATIENTS 😂😂😂😂 LMAO
Are there other molecules that don't affect tonicity other than urea?
Haha I won't ever forget the difference between osmolality and osmolaRity . Damn accents and clear confusion too !
Haha 😂
What a great explanation, love the vibe!
Thank you so much 😊
You are an extraordinary teacher, believe me you are better than my text book "Harrison" and "tietz"
Thank you so much ☺️
I don’t deserve any of that praise :)
Its Ok that practically Osmolarity and Osmolality is not that much different but hey what is "Osmolatity" at 4:23 :D just a mistake?
You’re right!
What great video! Thanks misteRRRR
In the slide at minute 1:26, it says both that Osmolality is per volume (l) and per mass (kg). Wrong? Because the first is the definition of osmolarity, right?
Osmolality is per kg.
Sir is the answer for problem Z at 6:56 is 30 Osmole/L
Is it osmolality or tonicity that affects the secretion of ADH? It is usually said that ADH is secreted by high osmolality, but it is confusing because Urea does not affect the secretion of ADH.
If I have high serum osmolality, it means that my serum is hypertonic, so both are correct!
SIRRRR, THANKYOU SO MUCHHHHH I CANT BELIEVEEE I NEVER KNEW WHAT ALL OF THIS BS MEANT UNTIL TODAYYY!
ALSO LOVE YOUUU! ALSO, HOW WOULD YOU DEFINE A SUBSTANCE THAT IS OSMOTICALLY ACTIVE?
WOULD MEAN A LOT IF YOU REPLY HEHE
A substance that can pull water towards it across a semi-permeable membrane.
Man i am arabian and i understand that very well thanks man
Came to this confused, left educated with a few laughs.
I appreciate you!
In this minute 4:17 you said that osm. Of IS =osm. of plasma= osm. Of ICF
But IS +plasma =ECF
And ECF osm.should equal ICF osm. How is this correct ?
You’re confusing volume with osmolality.
ECF volume = ISF volume + plasma volume.
However, all of them have equal osmolality.
Thanks a lot ❤
My pleasure!
i am so glad that i found your Channel , good job me🙂
Thank you 🙏
0.9 Ns osmolarity is 308.. Which is higher than plasma osmolarity... how it is isotonic fluid.. Plz explain
Isn’t osmolarity number of osmoles of solute in every liter of solution not solvent
Thank you once again.
You’re always welcome 🙏
You said for osmolality when you heat the weight will not change but on heating it is vapourized then how it will change the weight..it will reduce in weight
Assuming that you put the lid on 😊
underrated.
What's that cc used in 100cc
Cubic centimeters.
I wish my lectures were more like this💪🏿Urea is BS😂😂
Haha 😂
Thank you so much for watching!
I am honored!
Why in 1:33 you say osm/volume is osmolality
Though osmolality is osm/kg
You’re correct!
Why can’t molarity be used instead of osmolarity? I understand that osmolarity calculates the number of particles instead of molecules but I’m still not quite sure why can’t we use molarity?
Osmolarity is the osmosis caused by molarity.
I love this so much 😘😘
Thank you 🙏
3:10 now that make sense 😂😂
No osmometer is harmed during this video😁😁😁😁🤣
I believe I send you a message through Facebook? I’m not sure because I just created the account to ask you a to help me understand my test results
Thank you for trying to help me and answering to my comment in the other video
Thank you so much 😊
I’ve just replied!
i couldnt stop laughing at the hard Rs hahaha
Early 💜
Thank you so much ☺️
💜❤️
Thank you 🙏
Poor physiology professor 🤭
LOL 😂
only the bored people care hahah
Haha 😂
