Connective tissue is a specialized tissue that connects, supports, and stabilizes different structures within the body. While some types of connective tissue, such as bone and cartilage, have cells that are closely packed together, most connective tissues have cells that are widely separated from each other. The space between these cells is filled with a fluid matrix or extracellular material, which consists of various proteins, carbohydrates, and water. Examples of connective tissues with widely separated cells include loose connective tissue, adipose tissue, and blood.
