blood is considered to be a type of connective tissue. Even though it has a different function in comparison to other connective tissues it does have an extracellular matrix. The matrix is the plasma and erythrocytes, leukocytes and platelets are suspended in the plasma. Blood is a connective tissue consisting of cells suspended in an intercellular fluid (the blood plasma). Blood functions to transport oxygen, carbon dioxide, nutrients, wastes, hormones, etc. to and from the body’s cells. Blood cells consist of erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). The above picture is a smear of human peripheral blood. The numerous small reddish cells seen here are erythrocytes (each about 7 µm across, they are by far the most numerous type of blood cell). Note that in mammals, they do not have a nucleus when mature, which was lost during maturation in the bone marrow. Erythrocytes have a reddish colour (and, thus so does your blood) due to their
