Plasma, the liquid component of blood, has the same concentration of solutes as red blood cells. Both share similar osmotic pressure, which is crucial for maintaining fluid balance in the bloodstream. Additionally, isotonic solutions, such as normal saline (0.9% sodium chloride), are designed to match the concentration of red blood cells, preventing any net movement of water into or out of the cells.

What is the concentration of red blood cells?
The concentration of red blood cells in a healthy adult is typically around 4.5-6.0 million cells per microliter of blood. This concentration can vary slightly based on factors such as age, sex, and altitude.
Why does dehydration result in a raised red blood cell concentration?
Dehydration leads to a decrease in blood volume, causing the red blood cell concentration to appear higher than usual. This is because the same number of red blood cells are present in a smaller volume of blood.
Would osmosis have a higher concentration of water molecules distilled water or red blood cells?
Distilled water would have a higher concentration of water molecules compared to red blood cells. Red blood cells have solutes dissolved in them, so they have a lower concentration of water molecules relative to distilled water. This concentration gradient would result in osmosis moving water into the red blood cells to equalize the concentrations.
How do the diameter and concentration of bovine red blood cells compare to human red blood cells?
Bovine red blood cells are slightly larger with a diameter of about 6-8 μm compared to human red blood cells, which have a diameter of about 6-7 μm. The concentration of red blood cells in bovine blood is lower than in human blood, with a hematocrit of around 30-35% for cows compared to 40-50% for humans.
What Red blood cells that are bathed in blood neither shrink nor swell and burst If the concentration of blood is 0.5 M what could be the concentration of cytoplasm of RBCs?
The concentration of the cytoplasm of red blood cells is approximately 0.3 M, which is lower than the blood concentration of 0.5 M. This difference in osmolarity helps maintain the shape and integrity of the red blood cells by preventing them from shrinking or swelling due to osmotic pressure.
What concentration would use to store human red blood cells so that they would not shrink or swell?
You would need to use an isotonic solution. This one that has the same concentration of minerals as there is inside the cells.
Red blood cells with high oxygen concentration are bright red because?
They wear red shirts
What condition can result in an increased hematocrit?
Dehydration can lead to an increased hematocrit because there is a decrease in plasma volume while the amount of red blood cells remains the same, causing the overall concentration of red blood cells in the blood to increase.
Is potassium concentrated mroe in red blood cells?
The concentration of potassium within red blood cells is much higher than in the surrounding plasma or serum
Are red blood cells and blood the same?
They are not the same. White blood cells fight off infection while red blood cells carry much-needed oxygen throughout your body.
What will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells?
It's one of these answers: a. The red blood cells will absorb water and increase in size. b. The red blood cells will lose water and decrease in size. c. The red blood cells will first absorb water, then lose water and maintain their normal size. d. The red blood cells will first lose water, then absorb water, and finally double in size. A is wrong, just let you know. Still trying to figure out the answer myself.
How does carbon dioxide molecules reach red blood cells from respiring tissue?
Red blood cells have the responsibility of transporting oxygen throughout the body. About 33% of the weight of a red blood cell is attributed to a specialized protein called hemoglobin. Because of this, red blood cells are often referred to as "bags of hemoglobin."
