Answer

Blood is classified as a **connective** tissue because it contains living blood cells like **erythrocytes**, **leukocytes**, and **platelets** suspended in plasma. During centrifugation, the heavier cells settle at the bottom as the **formed elements**, and their volume is measured by the **hematocrit**. The lighter **plasma** floats to the top, making up about **55%** of the blood volume. The **buffy coat**, which includes **leukocytes** and **platelets**, forms a thin layer in between and accounts for less than **1%** of the blood volume.

In terms of its tissue classification, blood is classified as a connective tissue because it has living blood cells, called erythrocytes, suspended in a nonliving fluid matrix called plasma. The "fibers" of blood only become visible during clotting. If a blood sample is centrifuged, the heavier blood cells become packed at the bottom of the tube. This compacted cell mass is composed of leukocytes and platelets, and the volume of blood accounted for by these cells is referred to as the hematocrit. The less dense plasma rises to the top and constitutes about 55% of the blood volume. The so-called "buffy coat" composed of leukocytes and platelets is found at the junction between the other two blood elements. The buffy coat accounts for less than 1% of blood volume.
