APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Endothelial cells form a single cell layer that lines all blood vessels and regulates exchanges between the bloodstream and the surrounding tissues.

Detailed explanation-2: -The tunica intima consists of a layer of endothelial cells lining the lumen of the vessel, as well as a subendothelial layer made up of mostly loose connective tissue.

Detailed explanation-3: -Endothelial Cell Types There are four major organism-wide ECs which are arterial, venous, capillary, and lymphatic ECs (Fig. 1) [5]. Overview of the various endothelial cells examined for heterogeneity including a comparison of four organism-wide ECs which are arterial, venous, capillary, and lymphatic ECs.
