Explanation:
In terms of its tissue classification, blood is classified as a ____CONNECTIVE______tissue because it’s extracellular matrix determines its function. Blood is composed of living blood cells, called formed substances, suspended in a nonliving fluid matrix called ___PLASMA________. The "fibers" of blood only become visible during ______INJURY____________. When blood is centrifuged, the plasma is less dense and rises to the top. It makes up ___55%_____ of whole blood. The other 45% is comprised of 3 formed elements, scientifically they are called: ____RED BLOOD CELLS_______ (RBC), _____WHITE BLOOD CELLS____ (WBC) and ____THROMBOCYTES_____(platelets). The heavier blood cells become packed at the bottom. Most of the bottom is composed of _____ERYTHROCYTES___________. The "buffy coat" separates these two areas. It is composed of ____LEUKOCYTES______ and ___PLATELETS_______.
