What do we call specialized cells that work together

Each tissue type has a specific function. For example, epithelial tissue covers the body's surface. There are different types of epithelial tissue, including columnar and cuboidal.While muscular tissue is necessary for the movement of different body parts, connective tissue helps to anchor these body parts. Similar to epithelial tissue, there are different kinds of both muscle and connective tissues, such as smooth and skeletal muscles, and cartilage and blood tissues. Nervous tissue is a specialized type of tissue that reacts to different stimuli, and can conduct impulses to body organs.
