Which description of the movement of substances as tissue fluid forms is correct?
- ALow hydrostatic pressure forces substances out of the capillary at the arterial end allowing small substances to enter the fluid that bathes the cells.
- BTissue fluid moves back into the venule due to a net hydrostatic pressure change in the capillary.
- CMovement of water in tissue fluid into the capillary by osmosis is due to the low water potential and low hydrostatic pressure inside the capillary.
- DA high water potential of the surrounding tissue fluid causes substances to leave the capillaries at the arterial end.
