What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as another solution, resulting in no net movement of water across a semipermeable membrane.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, causing water to move out of a cell, leading to cell shrinkage.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing water to move into a cell, leading to cell swelling.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to animal cells in a hypertonic solution?

Back

Animal cells will shrink and may become crenated due to the loss of water.

Front

What happens to animal cells in a hypotonic solution?

Back

Animal cells will swell and may burst due to the influx of water.

Front

What is the effect of a 90% saline solution on human cells?

Back

Human cells will shrivel and potentially die due to the extreme hypertonic nature of the solution.

Front

What is the normal saline concentration for isotonic solutions in the human body?

Back

The normal saline concentration for isotonic solutions in the human body is 0.9%.
