Capillaries.
capillaries
The blood vessels and the heart are lined by the endothelium! The heart is also lined by the epicardium, and is surrounded by the pericardial sac.
it is called Endothelium (endothelial layer) composed of simple squamous epithelium forming a countinuous barrier.

The blood vessels and the heart are lined by the endothelium! The heart is also lined by the epicardium, and is surrounded by the pericardial sac.
If stratified squamous epithelium lined the blood vessels, gas and nutrient exchange across the vessel walls would become much more complex, requiring multiple transports and making the process much more energy intensive.
Blood vessels are lined with simple squamous epithelium--in fact, the entire cardiovascular system is.
The thick layer of a vein is made of collagen, wrapped in bands of smooth muscle while the interior is lined with endothelial cells called intima.
A thin, single-celled, layer of squamous endothelial tissue overlapped inside by an interlacing network of other cell tissue. There are two more layers on top of this inner layer.
In an average person, all the blood vessels, veins, arteries, and capillaries lined up one to the other can go around the world at least twice.
