Formation of tissue fluid pt 2

Question 1

When blood is at the arteriole end of a capillary, the hydrostatic pressure is great enough to …………

Answer 1

push molecules out of the capillary

Question 2

When blood is at the arteriole end of a capillary, the hydrostatic pressure is great enough to push molecules out of the capillary

Proteins remain in the blood; the increased protein content creates a …………… between the capillary and the tissue fluid

however the overall movement is…………

Answer 2

Water potential gradient

However, overall movement of water is out from the capillaries into the tissue fluid

Question 3

At the venule end of the capillary, less fluid is pushed out of the capillary as…….

Answer 3

pressure within the capillary is reduced

Question 4

At the venule end of the capillary, less fluid is pushed out of the capillary as pressure within the capillary is reduced

The water potential gradient between the capillary and the tissue fluid remains the same as at the arteriole end, so water begins to………….

Answer 4

flow back into the capillary from the tissue fluid

Question 5

Overall does more fluid leave the capillary or tissue fluid

Answer 5

Overall, more fluid leaves the capillary than returns, leaving tissue fluid behind to bathe cells

Question 6

If blood pressure is high (hypertension) then the pressure at the arteriole end is even greater

This pushes more fluid out of the capillary and fluid begins to accumulate around the tissues. This is called ………

Answer 6

oedema
