The article “The Subcategories of the Major Tissue Types in Anatomy and Physiology” by Robert Mullis talks about the different kind of major tissues in the human body. Tissue is a group of similar cells working together. There are four types of tissue that do different things: Epithelial, Connective,Muscle and Nervous. For example, the essential functions of epithelial tissues are secretion, absorption, protection, filtration, and excretion.

Another major tissue is the connective tissue, which functions include binding support, protection, insulation, and transportation. Muscle tissue is as well a major tissue, and its
