What does isotonic mean in biology?
Isotonic solution: A solution that has the same salt concentration as cells and blood.
What is a hypertonic solution in biology?
Definition. A solution that has higher osmotic pressure (or has more solutes) than another solution to which it is compared. Supplement. When a cell’s cytoplasm is bathed in a hypertonic solution the water will be drawn out of the cell and into the solution by osmosis.
What does Hypotonicity mean in anatomy?
British Dictionary definitions for hypotonic hypotonic. / (ˌhaɪpəˈtɒnɪk) / adjective. pathol (of muscles) lacking normal tone or tension. (of a solution) having a lower osmotic pressure than that of a specified, generally physiological, solutionCompare hypertonic, isotonic.
What is isotonic example?
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.
What is isotonic anatomy?
isotonic: Of or involving muscular contraction against resistance in which the length of the muscle changes. Antonym is isometric. Isotonic movements are either concentric (working muscle shortens) or eccentric (working muscle lengthens).
What is osmosis in biology examples?
Examples of Osmosis: Examples of osmosis include red blood cells swelling up when exposed to fresh water and plant root hairs taking up water. To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.
What is osmosis and diffusion in biology?
Osmosis is the movement of solvent particles from a solution that is diluted to a more concentrated one. In contrast, diffusion is the movement of particles from a higher concentration region to a region of lower concentration.
What is Hypotonicity simple?
1 : having deficient tone or tension hypotonic children. 2 : having a lower osmotic pressure than a surrounding medium or a fluid under comparison hypotonic organisms.
What is hypertonic cell?
Hypertonic means that the environment outside of the cell has a higher concentration of solutes than the cell itself. That will attract water molecules from the cell leading to the shrinking of the cell.
What is hypotonic example?
A hypotonic solution is a solution that has a lower concentration of solute compared to the cell. A hypotonic solution example is salt water. The salt is the solute, and the water is the solvent.
What does hypotonic mean in biology?
Hypotonic Definition. Hypotonic can mean several things in biology. Its many definitions apply to both human biology and biochemistry. When referring to humans or animals, hypotonic signifies a muscle’s having less tone, or shape, compared to a normal comparison model or when compared to another muscle in the same human body.
Why use hypotonic IV solutions?
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.
When is hypotonic solution used?
For hypotonic solutions, it can be used for treatment of dehydration and hypernatremia, or increased sodium in the blood. Hypotonic solutions act on the body by letting the cell absorb water thus it will cause swelling. Since the solute in hypotonic solutions is less, water will shift from the solution into the cell.
What are some examples of hypotonic solutions?
Hypotonic Solution Hypotonic Solution Definition. A hypotonic solution is a solution that has a lower solute concentration compared to another solution. Examples of Hypotonic Solution. Large plants and fungi control the environment around their cells, helping ensure the environment is always a hypotonic solution, compared to the cells. Related Biology Terms. Quiz.
