What is meant an organ is always made of tissue but a tissue is not always considered an organ?

Answer:
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.
