Red blood cells do contain some salts and other ions inside the cell. This means that if it is placed in water (assuming that it is deionized and has no solvent in it) the cell will be hypotonic because the concentration inside the cell will be higher than it is outside the cell.
A solution with more salt/solutes than the fluid inside the red blood cells.
Yes, and this can cause the cell to explode. This is not life threatening however, because we have skin cells to protect us.
Normal Saline 0.9% is called an isotonic solution. A 0.0% saline solution is called a hypotonic solution. A solution of this concentration would cause water to diffuse into the red blood cells and cause them to burst open. A 10% saline solution is called a hypertonic solution. A solution of this concentration would cause water to diffuse out of the red blood cells, making them shrivel up and shrink.
Hemolysis is the bursting of red blood cells (hemo- blood and lysis- bursting). There are three types of solutions that blood can be put into: hypertonic, hypotonic and isotonic. The names of these give you some clue as to how the cell will behave in solution. Hypertonic solutions have greater osmotic pressure than the cells they contain, which will cause the cell to shrivel as its contents diffuse into the solution. Hypotonic solutions have less osmotic pressure than the cells inside of them, so the contents of solution will diffuse across the cell membrane and into the cell, eventually causing it to swell and burst (hemolysis). Isotonic solutions have osmotic pressure equal to that of the solutes they contain, so no net change is observed.
An isotonic solution for human red blood cells is .85% sodium chloride. When the osmotic pressure is the same outside the cells and inside the cells, the solution is isotonic.
water would move from the red blood cell into the solution and the cell would then shrink and therefore not function properly
Red blood cells in a hypertonic solution will shrink. This occurs as water moves out of the red blood cell.
Hypertonic
Yes, because there is no sodium in the solution.
9% NaCl is a hypertonic saline solution. Red blood cells will appear to shrink as they lose water out of the cell membrane and into the saline solution.
There are two types of solutions categorized by solute concentration. If the solution has a higher saline concentration than the erythrocytes (red blood cells) it is said to be hypertonic. If the opposite is true the solution is then hypotonic.
The water will flow out of the cell into the hypertonic solution and the red blood cell will crenate (crush).
A hypotonic solution will be anything with less than 0.9% salt.
the red blood cells will shrivel and collapse since NaCl is hypertonic compared to the red blood cells.
Hypertonic
Crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis.Hemolysis is the breakdown of red blood cells.
Yes, and this can cause the cell to explode. This is not life threatening however, because we have skin cells to protect us.
It is hypotonic.
