What type of specialized tissue is blood?

Blood is a specialized form of connective tissue. It consists of cells—red blood cells, white blood cells, and platelets—suspended in a fluid extracellular matrix called plasma. This fluid matrix is what makes blood a fluid connective tissue, allowing it to function as the body's transport system, carrying gases, nutrients, wastes, hormones, and immune cells throughout the vessels. The tissue also plays a role in clotting and protecting against infection. This is not nervous tissue, which is built for rapid electrical signaling between body parts; nor epithelial tissue, which lines surfaces and cavities; nor muscle tissue, which specializes in contraction and movement. Blood’s primary job is transport and defense within a fluid matrix, fitting the definition of a fluid connective tissue.
