Inner lining of blood vessels is formed by

ciliated epithelium

squamous epithelium

cubical epithelium

columnar epithelium

squamous epithelium

Inner lining of blood vessels is formed by squamous epithelium. It consists of a layer of thin, flat, scale- like cells with prominent nuclei. The cells have irregular boundaries that fit closely into those of neighbouring cells.

Ciliated epithelium is found in the respiratory tract and in the fallopian tubes of women. It helps in the movement of particles out of the body using hair like structures, cilia.

Cuboidal epithelium is found in organs that are specialized for secretion such as salivary glands and thyroid follicles.

Columnar epithelium is uni- layered. It is found in lining of most of the digestive tract such as stomach, small intestine and large intestine.
