Examples of hypotonic in the following topics:
-
- There are three types of dehydration: hypotonic or hyponatremic (primarily a loss of electrolytes, sodium in particular), hypertonic or hypernatremic (primarily a loss of water), and isotonic or isonatremic (equal loss of water and electrolytes).
- In humans, the most commonly seen type of dehydration by far is isotonic (isonatraemic) dehydration which effectively equates with hypovolemia, but the distinction of isotonic from hypotonic or hypertonic dehydration may be important when treating people who become dehydrated.
- In hypotonic dehydration, intravascular water shifts to the extravascular space, exaggerating intravascular volume depletion for a given amount of total body water loss.
- Neurological complications can occur in hypotonic and hypertonic states.
- Solutions used for intravenous rehydration must be isotonic or hypotonic.

- Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells .
- In a hypotonic situation, the extracellular fluid has lower osmolarity than the fluid inside the cell, and water enters the cell.
- Blood cells and plant cells in hypertonic, isotonic, and hypotonic solutions take on characteristic appearances.
- Cells in a hypotonic solution swell as water enters the cell, and may burst if the concentration gradient is large enough between the inside and outside of the cell.
- Osmotic pressure changes the shape of red blood cells in hypertonic, isotonic, and hypotonic solutions.
-
- There are three types of tonicity: hypotonic, hypertonic, and isotonic.
- In a hypotonic environment, water enters a cell, and the cell swells.
- Some organisms, such as plants, fungi, bacteria, and some protists, have cell walls that surround the plasma membrane and prevent cell lysis in a hypotonic solution.
- In fact, in plants, the cellular environment is always slightly hypotonic to the cytoplasm, and water will always enter a cell if water is available.
- Freshwater fish live in an environment that is hypotonic to their cells.
-
- A cell immersed in plain water tends to swell as water diffuses in from the hypotonic or "low salt" solution .
- Response of red blood cells in hypertonic, hypotonic, and isotonic solutions
- In a hypotonic environment, cells tend to swell due to intake of water.
-
- If the medium is hypotonic — a diluted solution with a higher water concentration than the cell — the cell will gain water through osmosis .
-
- In relatively hypotonic (low osmotic pressure) fresh water, their skin absorbs water (see [a] in ).
-
- The solution that has the higher concentration of solutes is said to be hypertonic and the solution that has the lower concentration of solutes is said to be hypotonic.
- Water molecules will diffuse out of the hypotonic solution and into the hypertonic solution (unless acted upon by hydrostatic forces).
-
- Therefore, the introduction of saline that is too hypotonic will cause water to fill the cells too rapidly, potentially causing the cells to burst.
-
- As a result, when a cell is placed in a hypotonic solution, water rushes into the membrane, increasing its volume.
