Capillary walls consists of a single layer of flat endothelium
A single thin layer of endothelium is called a monolayer.
Tunica Intima is the innermost layer of the wall of the artery. The wall is consist of simple squamous epithelium which is called endothelium.
It lines the lumen of the vessels, and is a thin layer of endothelium.
Endothelium, which is the innermost layer of all blood vessels.
endothelium
The endocardium is the layer of the heart wall that is made up of endothelium overlying connective tissue. This layer lines the interior of the heart chambers and valves, providing a smooth surface for blood flow.
The innermost layer of epithelial cells of a blood vessel is called endothelium.
Single layer of Simple Squamous Epithelium
→ layers from alveolus to capillary ①surfactant layer (inside alveolus) ②pneumocyteⅠ(typeⅠ cell) layer ③fused basal lamina (consists of basal laminae of alveolar epithelium and capillary endothelium) ④endothelium (inside capillary)
it is called Endothelium (endothelial layer) composed of simple squamous epithelium forming a countinuous barrier.
The serous endothelium is called mesothelium. It is a single layer of flat cells that line the body cavities and cover the organs within them. It helps to reduce friction between the organs during movement.
There is no layer of ozone layer i.e. distinction. It does not consist of any layer, only a single layer is there.
