That IV is full of saline, a liquid with the same concentration of solutes as your blood cells. Because you want your blood cells to sit in an isotonic solution. An isotonic solution is when two solutions, separated by a semipermeable membrane, have equal concentrations of solutes and water.
Also asked, what is the difference between hypertonic and hypotonic solutions?
When a cell is immersed into a hypertonic solution, the tendency is for water to flow out of the cell in order to balance the concentration of the solutes. Likewise, the cytosol of the cell is conversely categorized as hypotonic, opposite of the outer solution. Hypotonic refers to a lesser concentration.
Is water hypertonic hypotonic or isotonic?
Blood is isotonic. Hypertonic solutions have less water ( and more solute such as salt or sugar ) 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 IV solutions are hypertonic?
IV fluid tonicity
|0.9% NaCl (normal saline)||isotonic|
|Lactated Ringer's solution||isotonic|
|D5W (acts as a hypotonic solution in body)||isotonic|
