Connective tissue, as its name implies, binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous. Lymphocytes, such as T cells and B cells, have their specific binding sites that allow them to recognize and attach to antigens that have entered the body. What are the signs and symptoms of dementia? Regulatory T-cells dampen the immune system response. Each of these lineages of embryonic cells forms the distinct germ layers from which all the tissues and organs of the human body eventually form.
