Water Moves Into and Out of Cells by Osmosis Flashcards
What surrounds the cells in the body?
Tissue fluids
What is tissue fluid?
Water with oxygen, glucose and stuff dissolved in it
What is the tissue fluid squeezed out of?
The blood capillaries to supply the cells with everything they need
What will the tissue fluid have different to the fluid inside a cell?
A different concentration
How will water move into the cell?
From the tissue fluid
How will water move out of the cell?
By osmosis
What happens if a cell is short of water?
The solution inside it will become quite concentrated
What does this mean (concentrated solution)?
Solution outside is more dilute, and so water will move into the cell by osmosis
What happens if a cell has lots of water?
The solution inside it will be more dilute , and water will be drawn out of the cell and into the fluid outside by osmosis
