1. Blood is a connective tissue because it transports oxygen and other substances within the body to different organs. Blood is an extracellular matrix tissue in which various cells are suspended in the plasma. These are Red Blood Cells (RBCs), White Blood Cells (WBCs) and platelets. The extracellular matrix is made up of these cells suspended in a liquid called plasma.
