The pressure of blood inside the capillary forces water out of the blood and into the interstitial spaces.

This force is called:

• hydrostatic pressure

• osmotic pressure

High solute concentration inside the capillary draws (pulls) water back into the blood from the interstitial spaces.

This force is called:

• hydrostatic pressure

• osmotic pressure

Which type of solution has the same solute concentration inside of and outside of the cell?

• Hypertonic

• Hypotonic

The cell shrunk in size, which means it was placed in a ____ solution.

• Isotonic

• Hypertonic

• Hypotonic

Which process involves the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration?

• Osmosis

• Diffusion

• Facilitated diffusion

• Active transport
