Epithelial tissue is characterized by its sheet-like structure with one surface always facing a body cavity or an external environment. This tissue type is responsible for protecting the body's internal and external surfaces from physical and chemical damage, and it can also regulate the exchange of substances between the body and its environment. Dense connective tissue is characterized by having a high concentration of collagen fibers, while loose connective tissue has a lower density of fibers and contains more cells and ground substance. Muscular tissue is composed of cells that are specialized for contraction and movement, while nervous tissue is responsible for transmitting electrical signals throughout the body.
