What is an isotonic solution in the human body?

Last Updated: 3rd March, 2020

Isotonic is a term used to describe solutions and chemistry and, sometimes, muscles in human biology. In chemistry, a solution is said to be isotonic when it has the same concentration of solutes as another solution across a semipermeable membrane. The use of isotonic in human anatomy is used more rarely.

Keeping this in view, what is an example of an isotonic solution?

Common examples of isotonic solutions are 0.9% normal saline and lactated ringers. These fluids are useful when the patient has lost fluid volume from blood loss, trauma, or dehydration due to excessive nausea/vomiting or diarrhea.

Beside above, why would you give an isotonic solution? We give them an isotonic solution to try to expand the volume of their blood but we don't want it to necessarily move solvent out of the vein into their tissues. Conversely the hypotonic solution is used when we need to put fluids into the cells for example if your patient is in Diabetic Ketoacidosis and HERE.

Also to know, what is the definition of isotonic solution?

An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side.

How do you know if a solution is isotonic?

A solution is isotonic when its effective osmole concentration is the same as that of another solution. In biology, the solutions on either side of a cell membrane are isotonic if the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell.

What is a hypotonic solution?

A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.

Is water an isotonic solution?

Isotonic solutions have the same water concentration on both sides of the cell membrane. Hypotonic solutions have more water than a cell. Tapwater and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

What is a hypotonic solution example?

Examples of Hypotonic Solution
This creates cells that are turgid. The turgid cells push outward on their cell walls, which push against each other creating a rigid structure. The organisms are constantly cycling solutes, to keep the contents of their cells filled with water.

Is alcohol hypotonic or hypertonic?

More simply, whiskey is hypertonic to beer and beer, conversely, is hypotonic to whiskey.

Is Vinegar a hypotonic solution?

Vinegar in fact contains acetic acid and this reacts with the calcium carbonate making up the shell of the egg. If you add food coloring to the water you can see the process of osmosis in action as the coloured water passes into the egg. Water is known as hypotonic, ie. very dilute and contains more water than the egg.

What are the 3 types of solutions?

There are three types of solutions that can occur in your body based on solute concentration: isotonic, hypotonic, and hypertonic.

What is an example of hypertonic?

A solution of 5% dextrose (sugar) and 0.45% sodium chloride is an example of a hypertonic solution - so is a solution of 5% dextrose and 0.9% sodium chloride. An example of a hypertonic solution that has glucose dissolved into it is any plain glucose solution with a concentration higher than 5%.

What does hypertonic mean in biology?

A hypertonic solution (pronounced "HĪ-per-TAWN-ik") is a solution with a higher concentration of solute (dissolved substance) than some other, specified solution (and which therefore has a higher osmotic pressure than the other solution). The solution with the lower concentration is then termed hypotonic.

Why are cells hypertonic?

Cells in Hypertonic Solutions
In a hypertonic solution the total molar concentration of all dissolved solute particles is greater than that of another solution, or greater than the concentration in a cell. As a result, water inside the cell will flow outwards to attain equilibrium, causing the cell to shrink.

What is isotonic and hypotonic?

In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Why do we use saline instead of water?

The reason normal saline, which is a 0.9% solution of NaCl in water, is used is that it is approximately isosmotic to plasma. If you were to infuse sterile water instead, water would travel into your blood cells and cause them to burst due to the differences in ion concentrations inside and outside of the cells.

What happens in an isotonic solution?

Cells in Isotonic Solutions
When two environments are isotonic, the total molar concentration of dissolved solutes is the same in both of them. When cells are in isotonic solution, movement of water out of the cell is exactly balanced by movement of water into the cell.

Why is osmosis important to the human body?

The biological importance of osmosis is that it facilitates the distribution of essential nutrients in the body and the excretion of metabolic waste products. Cells have semipermeable membranes, and osmosis makes it possible for liquid solvents to pass through these cell membranes.

Kiowa Scherer


What are hypertonic solutions used for?

Examples of when hypertonic solutions are used include to replace electrolytes (as in hyponatremia), to treat hypotonic dehydration, and to treat certain types of shock. Solutions with a lower concentration of solutes than isotonic solutions are hypotonic.

What is isotonic solution Class 9?

If the medium surrounding the cell is of exactly the same water concentration as inside the cell, there will be no net movement of water across membrane resulting in no change in size of cell. Such solution is called Isotonic solution.

Abdelhay Milner


What is the difference between hypertonic and isotonic?

In biology, a hypertonic solution is one with a higher concentration of solutes outside the cell than inside the cell. An isotonic solution is one in which its effective osmole concentration is the same as the solute concentration of a cell.

Hocine Niedzielsk


Is osmosis active or passive?

osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.

Why would you give a hypotonic solution?

Hypotonic solution: A solution that contains fewer dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. Hypotonic solutions are commonly used to give fluids intravenously to hospitalized patients in order to treat or avoid dehydration.

What IV fluids are hypotonic?

* Commonly infused hypotonic solutions include 0.45% sodium chloride or 0.25% sodium chloride (with or without D5W). Potassium chloride may be added in low concentrations to replace losses from the gastrointestinal system.
