resting membrane potential is due to memberane permeability to K ions or active transport of Na and K ions(ans) bit i think ans shld be memb per to K as RMP is due to inc memn per to K than Na
http://en.wikipedia.org/wiki/Cell_potential
C/8
GENERATION OF AP is due to rapid but brief inc in Na conductance(ans) or K conductance?? isnt Ap generated when K inc or k channels open???
good to clear acidosis and alkalosis.... so sharing with u ..
http://www.elmhurst.edu/~chm/vchembook/263respiratoryacid.html
but i cant understand uncompensated and compensated like in this q E/34
normal hco3 and carbonic acid ratio is 20:1 a patient with 10:1 has comp acidosis or uncompensated acidosi.. i know the ans is acidosis.. but com / un comp?????
what is the fluid and what is the liquid portion of the blood... serum or plasma....??
99
33.organ using ketone bodiesas a major fuel in fed stage .. liver(ans acc to me) / muscle??// what say????
74
the 1stheart sound while detremining the BP is due to.. closure of AV valves or turbulant flow of blood through the artery
89.
gas mixture the potent stimulant for respiratory center
%O2 %CO2 N2
20 5 79.5
20 5 75
18 2 80
20 2 78
25 3 72 how to calculate this???/

correct me if i am wrong... but am bad in biochem physio...

the 1stheart sound while detremining the BP is due to.. closure of AV valves or turbulant flow of blood through the artery

sorry but i dint get the ques..

as far as i know, the heart sounds are 4 in no. 1st - closure of av valves
2nd closure of semilunar valves 3rd - turbulent flow of blood during the first rapid filling phase of ventricular diastole and the 4th - flow of blood in the last rapid filling phase of vent diastole or atrial systole..
whereas during measurement of bp we hear the kortokov's sounds in phases..
plz correct if reqd...

the palsma osmolality decrease after infusion of -
1 aldosterone
2 ADH
3 angiotensin 2
4 parathyroid hor

plasma osmolality is affected by change in water content.

some more inputs.....

some more inputs.....

Osmolality increases with dehydration and decreases with overhydration. In normal people, increased osmolality in the blood will stimulate secretion of ADH. This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma. A decreased serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma.
