In the human body, one of the most important connective tissues is blood. Blood is considered a connective tissue because it consists of a non-living fluid in which living cells are suspended. The blood matrix surrounding the cells is known as plasma, which accounts for about 55% of our blood volume.There are three types of living cells in blood: red blood cells (or erythrocytes), white blood cells (or leukocytes) and platelets (or thrombocytes). These make up the remaining 45% of our blood volume.n the human body, one of the most important connective tissues is blood.
