Updated August 02, They are given to patients with a buildup of fluid in their body issues known as edema to draw water away from the bloated tissues and back into the bloodstream. They are also used to replace electrolytes in the body of a sick and injured person who cannot consume food or liquids themselves.

Here are a few IV solutions that are considered hypertonic. Hypertonic saline describes any saline preparation with over 0. These patients include those with cystic fibrosis and severe bronchitis. It draws fluid out of cells to prevent cerebral edema. Water with a large amount of dextrose can be an effective way to replace fluids and calories in an IV drip.

This hypertonic solution is helpful for babies who are at risk for hypoglycemia low blood sugar. There can be some confusion over the terms hypertonic, hypotonic and isotonic. They all relate to the concept of tonicity, which is the concentration of a solution compared to another solution. The three types of tonicity are:.

This tutorial provides elaborate details on each of these mechanisms. Find out how. Skip to content Main Navigation Search. Water moves into and out of cells by osmosis. A red blood cell will swell and undergo hemolysis burst when placed in a hypotonic solution. When placed in a hypertonic solution, a red blood cell will lose water and undergo crenation shrivel.

Animal cells tend to do best in an isotonic environment, where the flow of water in and out of the cell is occurring at equal rates. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion or simple diffusion , osmosis, and facilitated diffusion.

Simple diffusion and osmosis do not involve transport proteins. Facilitated diffusion requires the assistance of proteins. Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane. The difference in the concentrations of the molecules in the two areas is called the concentration gradient.

The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.

Diffusion will continue until the concentration gradient has been eliminated. Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient". The end result is an equal concentration, or equilibrium , of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.

At equilibrium, there is equal movement of materials in both directions. Not everything can make it into your cells. Your cells have a plasma membrane that helps to guard your cells from unwanted intruders.

If the outside environment of a cell is water-based, and the inside of the cell is also mostly water, something has to make sure the cell stays intact in this environment. What would happen if a cell dissolved in water, like sugar does?
