Why rouleaux formation does not occur in vivo?
When rouleaux formation is truly present, it is caused by an increase in cathodal proteins, such as immunoglobulins and fibrinogen.And the fibrinogen is not present in blood in vivo*This is not true. Fibrinogen is secreted by liver and is present in blood. The reason rouleaux do not form in vivo is that they only form under low shear stress conditions. With blood flow, the cross-sectional fluid velocity gradient in the blood vessel results in shear stress levels that exceed the threshold for rouleaux formation.
What is roulex formation?
This question probably is spelled wrong (roulex). A rouleaux formation is: A stacklike arrangement of red blood cells in blood or in diluted suspensions of blood in which their biconcave surfaces are next to each other.
Through what structure do red blood cells move in single file?
Capillaries. Red cells that group together normally tend to do so in rouleaux; those that stay as individuals will have greater opportunities to absorb oxygen. If they pass through capillaries individually will be more efficient as transporters of oxygen.
What are ice and steam forms of?
They are both forms of water.

What causes rouleaux formation?
The red blood cells stack up like coins. http://en.wikipedia.org/wiki/Rouleaux
What is mean by RBC's form rouleaux?
Rouleaux refers to the stacking of red blood cells (erythrocytes) in human blood. Rouleaux formation is enhanced in the presence of increased plasma proteins, leading to an increased erythrocyte sedimentation rate (ESR).
How is rouleaux formation differentiated from true agglutination?
Autoagglutination should also be distinguished from "Rouleaux formation" wherein normal blood tends to form stacks on keeping, which disperses on dilution with normal saline.

What medical conditions are related to rouleaux formation of the red blood cells?
Multiple Myeloma
What is the French word for spring rolls?
Spring rolls are "des rouleaux de printemps".
Which blood condition is characterized by the abnormal stacking of erythrocytes like a pile of coins?
rouleaux
What is the condition of red blood cells that appear like stacked coins?

What is 'rouleaux' when translated from French to English?
"Rollers" about surf-waves, for hair, or in painting, "rolling pins" in pastry, and "rolls" of paper, scrolls, and wallpaper are English equivalents of the French word rouleaux. Whatever the meaning or use, the pronunciation remains "roo-lo" in French.
What is rouleaux formation?
Rouleaux formation occurs when red blood cells form rolls or stacks. If not due to an artifact, such as a result of not preparing the blood smear soon enough after placing the blood on the slide, it may be due to the presence of high concentrations of abnormal globulins or fibrinogen. This formation is found in multiple myeloma and macroglobulinemia.
What is french for sleigh bed?
literally "un lit traîneau", but the old bed style "lit à rouleaux" also seems to fit.
