What is skin tissue made of?
The skin tissue is made of three main layers: the epidermis (suface), the dermis (subsurface), and a subcutaneous tissue (inside, where blood vessels run through)
Cells make up tissues and tissues make up organs, not the other way around. Every single organ in the body is made of some sort of organic tissue. This does not mean that all tissue is considered an organ. Tissue such as the Epidermis (skin), Muscle Tissue, Nervous Tissue, Epithelial Tissue, and Connective Tissue are Organic tissues that we do not consider to be Organs.
