in topic capillary exchange what is the value of k=filtration coefficient, and what is the value of reflection coefficient? thanx.

If the capillary is impermeable to protein then reflection coefficient = 1. and if it is freely permeable to protein, then ref coef = 0 filtration constant is determined by the physical properties of the barrier (i.e., size and number of pores and the thickness of the barrier). when u calculte these ques u dont need these values

can u calculate this q pls. Cp=+25mmHg Pif= -2mmHg oncotic prssure of capillary is = -20 and oncotic pressure of interstituim is= +1. so can u calculate it pls. thanx.

and answer in the book is +4. idon't know how? and if we calculate net pressure ,if the interstitial hydrostatic pressure is -2mmHg. pls reply me. thanx.

the ques in the book is Hc=25 Hi=2 OPc=20 OPi=1 net pressure=(25-2)-(20-1)=23-19=+4(net filtration) if Hi=-2 net press=(25-(-2))-(20-1)=27-19=+8(net filtration)

but mash u know according to capillary exchange Hi is always in (-) and oncotic pressure of capilary is also always in (-)b/c they support reabsorption. and also teacher said same thing in vidio lectures. i m still confuse yarr. pls help. thanx.

santaclara u cant change signs given in the ques... yeah u r right, if net pressure is -ve dat means reabsorption and +ve means filtration
