The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures.
What type of tissue is the epidermis classified as and why?
What type of tissue is the epidermis composed of? Stratified Squamous Epithelium. The epidermis is made up of stratified squamous epithelium. This stratification provides functional boundaries within the epidermis.

Which type of epithelial tissue is found in the trachea?
In general, the trachea is lined with ciliated pseudostratified columnar epithelium.
Which type of tissue would be found in the epidermis and form the lining of internal organs?
Where are epithelial tissues found in the body? In the epidermis; forms lining of internal organs. What are functions of the epithelial tissues? They line and cover the surfaces of internal organs.
What are epidermal and epithelial cells?
Epidermal cells is the outer most layer of skin. Epithelial cells is a layer of cells covering most of the organs separately. eg: epithelial cells of digestive system and epithelium of respiratory system. The epidermis itself consist of a layer of epithelial cells (epithelium) Biology.
What is the main tissue in the dermis?
The dermis has connective tissue, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis.
