CAIE A-Level Biology AS 8.1.9 Tissue Fluid Questions

any three from:

A $\Psi$ for water potential A plasma for blood

mp1 and mp2 = consequence in blood of lower blood albumin than normal

1 idea that low blood albumin means, less / AW, solute ;

2 (so) higher water potential (in blood);
must be in context of blood context can be anywhere along the capillary A high water potential if ref. to low albumin is made

A steeper water potential gradient (than normally, at arterial end)

mp3 and mp4 = return of water to blood from tissue fluid (capillary venous end)

3 less steep water potential gradient (than normal)/ little difference in water potentials ;

4 less / little, water returns to, blood / capillary (from tissue fluid) ;

A (tissue) fluid for water

R plasma for water

additional ideas

5 idea that more, water / plasma / fluid, enters tissue fluid (than normal)

R tissue fluid for fluid

A more, water / fluid, enters tissue fluid than exits (to the capillary or lymph system) ;
(compared to normal)

6 AVP ;
e.g. water can enter tissue fluid for a longer time than normal less albumin than normal to act as an osmotic force for return of water / AW too much excess, water / fluid / tissue fluid, to be taken up into lymph, capillaries / vessels / system
