Endothelial cells make up the endothelium which lines the inner surface of the lymphatic system, blood vessels and also the heart. Among their functions are coagulation, blood vessel formation, inflammation, relaxation of arterial smooth muscle and fibrinolysis.
There is a varying number between the amount of smooth muscle and connective tissue because different vessels that carry out distinct functions and have different structure. As an example, bigger diameter more smooth muscle and more connective tissues are available e.g. Artery.
