The water escapes as water vapor in a process called transpiration.

TRANSPIRATION-COHESION-ADHESION THEORY:

a). water exits leaf through stomata.
b). this water loss is replaced by evaporation from mesophyll cells, lowering their water potential, causing them to take water from neighboring cells.
c). the process connects back to the tracheids causing water to be taken from the xylem.
d).Water travels from the tracheids to the air following a water potential gradient.
e). Waters cohesive and adhesive properties and the small diameter of xylem aid in its movement of up the tube.
f). This pull decreases water pressure in the xylem causing the roots to take water from the soil.

How Stomata Operate:

Turgid guard cells open the stomata, while flaccid ones close them.
The potassium (K+) ion is responsible for the stomatal action.
Uptake of K+ causes the cell to become turgid decreasing its water potential.
The stomata open at dawn caused by the light inducing the cells to take in K+. An internal clock (circadian rhythm) will make them open even if in they are kept in the dark.
Guard cells will close due to water deficiency and high temperatures. It leaves the leaf as a gas (water vapor).

any water you drink will be absobed by blood and finally seperated in kidney and some parts evaporates through the skin.

water vapor?
transpiration?
It's hard for me to tell what you want.
