Key Concepts: The prefix hyper- refers to “high” as in hypertension (high blood pressure) A hypertonic solution has a higher amount of solute (the solid that is being dissolved) and a lower amount of solvent (the liquid that is dissolving the solute)
What happens to RBC in hypertonic solution? – Sage-Advices
Hypertonic Solution Hypertonic: The solution has a higher concentration of solutes and a lower concentration of water than inside the cell (High solute; Low water)? Result: Water moves from inside the cell into the solution: Cell shrinks (Plasmolysis)! • Osmosis Animations for isotonic hypertonic and hypotonic solutions shrinks

306 Isotonic Hypotonic & Hypertonic Notes
Hypotonic solutions are used when the cell is dehydrated and fluids need to be put back intracellularly This happens when patients develop diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemia Important: Watch out for depleting the circulatory system of fluid since you are trying to push extracellular fluid into the cell to re-hydrate it

Cells hypertonic to their surrounding solutions cause water to move into the cell and cause it to expand The cell has a higher number of particles (solutes) dissolved in it than the solution outside of the cell membrane This causes turgor pressure in plants that make the plants rigid for support
What happens to a cell in a hypertonic solution?
- Hypertonic solutions cause cells to shrivel and shrink in size, which can cause problems and inhibit proper cell functioning. When solutions surrounding cells are hypertonic, this will cause the organism to become dehydrated, which can lead to problems such as organ failure. How does tonicity affect cells?
What is the difference between a hypertonic solution and a hypotonic solution?
- A hypertonic solution has high osmotic pressure, whereas a hypotonic solution has low osmotic pressure. The concentration of solute is more in hypertonic solution than the hypotonic fluid. The concentration of solvent is low in hypertonic and high in hypotonic. Is hemolysis good or bad?
What are some common hypertonic solutions?
- Common examples of hypertonic solutions are D5 in 0.9% normal saline and D5 in lactated ringers. The administration of hypertonic solutions should be monitored extremely closely, as they can quickly lead to fluid overload. Can blood cells burst? Red blood cell lysis is more commonly known as hemolysis, or sometimes haemolysis.
What are the effects of a hypertonic solution on plant cells?
- Hypertonic solutions make plant cells lose water. Hypertonic solutions have a higher solute concentration. When plant cells are placed in such solutions, water will move from inside the plant cell to the outside of the cell, resulting in the shrinking of the cell (the cell is said to be plasmolyzed). This occurs because of osmosis.
