Sir basically it means we have to know the na+ and h2o conc of extracellular fluid after any addiction or substraction of fluid....and for that we also have to know conc of both in sweat,sea water,normal water...provided unaware of the conc of the fluid we may make mistake while answering such mcqs
Sea water osmolarity is 2400 mosm/L. Maximum concentrating ability of kidney 1200 mosm/L. So..if osmolarity of consumed fluid 1200 mosm/L- Hypertonic dehydration. So last question answer is hypertonic dehydration.plz reply.
In addisons there is sodium excretion and so the osmolality is decreasing in ecf. If so, the ecf is concentrated and water has to move from icf into ecf right?? Plz explain
@@ThePhysiologyChannel sir i have a doubt i was reading mechanism of action of baro receptors and it was mentioned that they decrease hr as well as bp through negative feed back but in cushings reflex they only decrease hr .Bp remains high how is it so ? I am a little confused
Hi Shobhit, This paradox is because two different actions are taking place simultaneously. Cerebral ischemia due to raised ICT increases sympathetic activity on heart and blood vessels (Both HR and BP increases). As a secondary effect due to rise in BP, baroreceptor reflex gets activated which decreases sympathetic activity and increases vagal activity. Increase in vagal activity on SA node decreases HR but, the sympathetic vasopressor response due to cerebral ischemia is more powerful, so BP remains high.
So much more helpful than my medical school professor. Thank you so much.
Glad to hear it was helpful!
revising for neet pg and found this gem !!! Thank you Sir !!

Sea water osmolarity is 2400 mosm/L.
Maximum concentrating ability of kidney 1200 mosm/L.
So..if osmolarity of consumed fluid 1200 mosm/L- Hypertonic dehydration.
So last question answer is hypertonic dehydration.plz reply.
Yes I also thought the same..
Thank you sir!!
You’re welcome 😊
what would be the changes in ECF and ICF compartments in CHF/nephrotic syndrome/cirrhosis? please explain the mechanisms
In addisons there is sodium excretion and so the osmolality is decreasing in ecf. If so, the ecf is concentrated and water has to move from icf into ecf right?? Plz explain
If sodium is removed from ECF, it gets diluted, not concentrated.becoz you are removing solute from solution
