Four types of tissues are formed as cells join and function as a group. Each type of tissue has a distinctive structure and performs a specific job. Muscle tissue is composed of long and narrow muscle cells that enable body parts to move by contracting and relaxing. Connective tissue supports the body and connects its parts together; for example, bones are made up of connective tissue. Nerve tissue consists of long nerve cells that branch throughout the body, carrying messages. Epithelial tissue is composed of wide, flat epithelial cells and lines the internal surfaces of the body, forming the outer layer of the skin. Groups of tissues come together to form organs in our body, such as the heart, liver, lungs, brain, and kidneys. These organs then collaborate to form our body systems, each system working in complete coordination with others.

In a chart, Mary wishes to summarize the crucial information about each tissue type. Which two pieces of information should be listed in the chart beneath the muscular tissue?
