If you place a sample of your blood (which is primarily red blood cells) in a beaker of distilled water, what do you think would happen to the RBCs? Why? Is water moving into or out of the cells? Is the water hypotonic, isotonic, or hypertonic compared to the intracellular fluid in the RBCs? Knowing that normal cellular osmolarity is 300 mOsmol, what do you think would happen if you mixed your RBCs with a 1.8% NaCl solution? Why? What is the osmolarity of the 1.5% NaCl solution? RBCs with distilled water and why Is water moving into or out of the RBCs in this solution? Is the water hypo-, iso- or hypertonic?

Fill in the blanks with the appropriate word from the following group: hemolysis, water, increase, crenation, decrease, isotonic. The RBC’s in Figure 8.7 “a” are suspended in an (blank1) solution. If red blood cells are placed in a hypertonic solution they lose (blank2) and (blank3) in size. This process is called (blank4). If red blood cells are placed in a hypotonic solution they gain (blank5), (blank6) in size, and may burst. This process is called (blank7).
The volume of a red blood cell will remain unchanged in... 1) distilled water, a isotonic solution 2) 150 mM NaCl, an isotonic solution 3) 150 mM glucose, an isotonic solution 4) 150 mM MgCl2, an isotonic solution
What would happen if red blood cells were placed in a beaker of distilled water. Why?
A red blood cell with an internal solute concentration of 3% was placed in a 0.3% saline solution. What would you predict to happen to the red blood cells?
Why is it important to know the isotonic point of human cells when administering an IV? Explain what would happen to the red blood cells if an IV solution were hypotonic or hypertonic.
Describe the reason why the red blood cells placed in one solution swell and burst and also why the red blood cells placed in another solution shrink and wrinkle.
Blood volume must be restored in a person who has lost large amounts of blood due to serious injury. This is often accomplished by infusing isotonic NaCl solution into the blood. Why is this more effective than infusing an isoosmotic solution of a penetrating solute, such as urea?
On your bench, there are two tubes, Tube X and Tube Y. One tube contains 1.2 mL of 300 mosm Sucrose, and the other tube contains 1.2 mL of 300 mosm Urea. After adding 20 ul of blood to each tube, you observed the hemolysis in Tube X, but not in Tube Y. Which of the following two tubes contains Sucrose or Urea? Tube X = Tube Y = If the 2 solutions have the same osmolarity, explain how can they lead to different cell responses?
What happens to a red blood cell in a hypertonic, isotinic and hypotonic solution? How is the absorbance changing?
Explain what would happen to a red blood cell that is placed in the following solutions: a) Hypertonic solution b) Isotonic solution c) Hypotonic solution (Minimum words 60)
If a blood cell shrinks after being placed in a solution, what can we conclude about the solution?
You are a doctor in the emergency room. You have a patient whose blood cells are composed of the following: 80 molecules of glucose, 50 molecules of hemoglobin, 20 molecules of dextrose, and 2000 molecules of water. a. What is the total solute concentration of her cells? b. If you needed to make an isotonic solution of saline for her IV, how many salt molecules would you need to add to 1000 molecules of water? How do you know this is the correctamount?
