Document Summary
Hundred trillions of cells, there are only about 200 types of them are recognized. It"s the combinations of these types to come together and form the tissue of the body. Tissues are collections of specialized cells and cell products that perform a specific function. Organs are formed by two or more tissues that are united in patterns to perform a series of specific functions. Systems are formed by an interacting group of organs that performs one or more specific functions essential for the well-being of the organism. Basic tissues: epithelial tissue, connective tissue (including cartilage, bone, blood, muscle tissue (smooth, cardiac, skeletal, nerve tissue. Epithelium is a tissue composed of closely apposed cells with very little or no intervening intercellular substance. Tissue in which the cells that make up the tissue are really closely packed together. Those cells don"t have much space in between.
