Study Notes
Endothelial Cells and Smooth Muscle Contraction
- Endothelial cells secrete substances to modulate the contraction of smooth muscle cells in the underlying medial layer.
Endothelial Cells and Inflammation
- Healthy arterial endothelial cells prevent leukocyte adhesion and inflammation.
Response to Injury or Infection
- Endothelial cells express adhesion molecules in response to local injury or infection.
Normal Endothelium Properties
- The normal endothelium is non-thrombogenic, non-adherent to leukocytes, and impermeable to macromolecules.
Function of Endothelial Cells
- The function of endothelial cells in blood vessels is to maintain vascular homeostasis, regulating vascular tone, immune response, and coagulation.
