A tissue is a :
Tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
Endothelium of the inner surface of blood vessels in vertebrates is formed
Cells of squamous epithelium are
The three principal shapes associated with epithelial cells are - squamous, cuboidal and columnar. Squamous epithelium has cells that are wider than their height (flat and scale-like). This is found as the lining of the mouth, oesophagus, the blood vessels and in the alveoli of the lungs.
The protein deposited in the dead superficial cells that make the skin epithelium impervious to water is
Horns of most mammals are composed of
Mammary glands are modified
These exocrine glands are enlarged and modified sweat glands and are the characteristic of mammals which gave the class its name. The basic components of the mammary gland are the alveoli (hollow cavities, a few millimetres large) lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells.

Dermis of mammalian skin is mainly composed of
The dermis forms the bulk of the mammalian skin. It is composed of an association of connective tissue fibres, mainly collagen, with a ground substance of mucopolysaccharide materials (glycosaminoglycans), which can hold a quantity of water in its domain.
