Detailed explanation-1: -The tunica intima (New Latin “inner coat"), or intima for short, is the innermost tunica (layer) of an artery or vein. It is made up of one layer of endothelial cells and is supported by an internal elastic lamina. The endothelial cells are in direct contact with the blood flow.
Detailed explanation-2: -The innermost layer of the vein is the tunica intima. This layer consists of flat epithelial cells. These cells allow fluid to flow smoothly and are interspersed with valves that ensure the flow continues in one direction. This continuous layer of epithelial cells holds cells and fluid within the vessel lumen.
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.
