Accepted Answer

The tunica intima, also known as the intima layer, is the innermost layer of blood vessels. It is composed of a simple squamous epithelium known as endothelium and loose connective tissue. The endothelium provides a smooth surface for blood flow and helps maintain the permeability of the blood vessels. The loose connective tissue includes collagen and elastin fibers that support and anchor the endothelium in place.
