Thrombosis, atherosclerosis, and hypertensive vascular lesions.
Endothelial cells form the inner lining of a blood vessel and provides an anticoagulant barrier between the vessel wall and blood. Endothelial cells also generate an antithrombotic surface that facilitates transit of plasma and cellular constituents throughout the vasculature. As a selective permeability barrier, the endothelial cell is a unique multifunctional cell with critical basal and inducible metabolic and synthetic functions. The endothelial cell reacts with physical and chemical stimuli within the circulation and regulates hemostasis, vasomotor tone, and immune and inflammatory responses. In addition, the endothelial cell is pivotal in angiogenesis and vasculogenesis.
Endothelial and epethelilal cells are the two different cell types which sandwich together the tissue. On the blood side is the endothelial cells (endo, meaning inside), and on the outer side are the epethelial cells. For example the epethelial cell layer are the cells that coat the intetestine wall, and thus absorb nutrients and the the endothelial cells are the cells that face the blood,and release those nutrients into the blood.
Endothelial cells also known as epithernal tissue.
the dysfunction affects the whole cell because if it wasn't there then the cells would die away slowly
(squamous) Arterial endothelial cells.

Caveolae are closely associated with cholesterol-rich lipid rafts in the cell membrane and are known to be involved in cellular signaling processes, vesicle trafficking, and lipid homeostasis. They also often play a role in endocytosis, particularly in endothelial cells and adipocytes.
Garvey is a lysosomal protein that plays a role in the trafficking and degradation of proteins in the endolysosomal system. It helps maintain cellular homeostasis by regulating protein turnover and degradation. Its dysfunction can lead to lysosomal storage disorders and other cellular pathologies.
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
Endothelial cells play a crucial role in inflammation by controlling the passage of immune cells and molecules from blood vessels to inflamed tissue. They regulate the expression of adhesion molecules and chemokines necessary for immune cell recruitment, contributing to the initiation and resolution of the inflammatory response. Additionally, endothelial cells can produce cytokines, which further promote inflammation and immune responses.
