What does "Fluid Shear Stress" mean?
Table of Contents
Fluid shear stress is the force that fluid (like blood) exerts on the surfaces it flows over, such as the inner walls of blood vessels. This force is important because it affects how cells in the blood vessels behave.
Importance in the Body
Endothelial cells, which line the blood vessels, are sensitive to fluid shear stress. When blood flows, these cells can feel the changes in force. This sensation helps them respond correctly to signals that regulate blood flow and overall heart health.
Effects on Endothelial Cells
When blood flow increases or changes, the endothelial cells adjust their activities. For example, they can change the way they take in materials from the blood or how they communicate with other cells. This adjustment is crucial for maintaining healthy blood vessels and preventing problems like heart disease.
Role in Research
Understanding fluid shear stress is important for scientists. It helps them learn how blood vessels function and how changes in blood flow can lead to health issues. By studying how endothelial cells respond to this stress, researchers can find better ways to treat cardiovascular diseases and improve drug delivery methods.
