When whole human blood is subjected to viscometric flow, individual red cells are seen to be elongated and oriented in the shear field. In addition, a tank tread-like motion of the membrane around the cell content occurs. In dilute suspensions of erythrocytes in viscous media, the same behavior is better observed and can also be measured quantitatively.
