What happens to fluid movement in the body when there are not enough plasma proteins in circulation?

Hydrostatic pressure decreases, resulting in fluid movement from the interstitial to the intravascular space.

Hydrostatic pressure increases, resulting in fluid movement from the intravascular to the interstitial space.

Osmotic pressure decreases, resulting in fluid movement from the intravascular to the interstitial space.
