Hypertonic solutions appear promising for acute resuscitation of hypotensive, brain-injured patients. If the blood-brain barrier (BBB) is intact, movement of water between the brain and the intravascular space is highly dependent on osmotic gradients, which may be established by the administration of ...
the solution (water) is hypotonic with respect to the interior of the red blood cells. The cells swell and may burst as water rushes into the cell to attempt to make the concentration of the interior and exterior solutions the same. Incidentally,...
When dealing with concentration gradients that affect the movement of water or particles, it is important to know the total number of particles per unit volume, regardless of their size. It is this, not total solute mass, that influences this movement, counterintuitive though this may be. For ...
Movement of water molecules across the cell membrane from hypertonic to hypotonic solution. View Solution What are isotonic solutions? View Solution Select the correct answer out of the four available choices given under question : The space between the cell wall and plasma membrane in plasmolysed ...
Recently, there has been a growing interest in hypertonic saline solutions, which act in the same way, exerting an osmotic effect, increasing the movement of water from the tissues into the circulatory system. The present study was to study the efficacy and safety of using 7% NaCl in the ...
Urea has an essential role in the generation of medullaryhypertonicity. The thick ascending limb of the loop of Henle is permeable to urea (and sodium) but not to water. Movement of urea down its concentration gradient into theinterstitiumcontributes significantly to medullary hypertonicity; the inne...
When the nose is blocked, it helps draw-out the excess water from the swollen nasal tissues, relieving congestion and restoring nasal breathing, naturally. This natural mechanism of water movement -in response to the difference in salt content between the solution and the nasal tissues-, is know...
but tonicity and the movement of water is very important for cells. Instead of two regions divided by a membrane, you can imagine a cell that is placed in a fluid. There are two regions: one inside the cell and one outside of the cell. The fluid outside of the cell is called the ...
Which type of solution (hypotonic or hypertonic) is formed in the soil environment around root cells when a lawn is over fertilized? Would the root cells lose or gain water? An animal cell in a ___ solution may lyse or burst open. a. ...
was used to fix a thick smear for 2 h before it was removed and allowed to air dry at room temperature for 5 min. The smear was then immersed in a stock solution of 1 mg acridine orange and 1000 mL distilled water, which was then kept in the dark at 4 °C for 5 min [48]. ...
