Connective tissue is the most abundant tissue type in the human body. Its primary function is to connect various tissues and organs. For example, a layer of connective tissue links the skin epithelium to the underlying muscle tissue. Connective tissue forms thin sheaths called fascia, binding and supporting internal organs and tissues. As seen in muscles, fascia wraps around the muscle and its fibers, stabilizing their organization. Additionally, bones, ligaments, and tendons are connective tissues that form the structural framework of the entire body. The ligaments connect two bones, while tendons attach muscles to bones. Fluid connective tissues include blood and lymph, which are responsible for the transport of nutrients and oxygen in the body and also help to eliminate waste. They also contain components of the immune system that protect the body from infections. Lastly, adipose, a specialized connective tissue, stores fat and protects internal organs from physical trauma. It also insulates the body and serves as an energy reserve.
