48. Squeezing of leucocytes out from the endothelium of capillaries to fight foreign agents is known as a.diapause b.diakinesis c.diapedesis d.didelphis
Haemolysis is the destruction of red blood cells so that the haemoglobin is freed into the surrounding medium. Diapedesis is the migration of blood cells, especially WBCs (leucocytes), through the intact walls of blood vessels into the surrounding tissue to fight foreign agents. Phagocytosis is the process by which phagocytes ingest or engulf other cells or particles. Rouleaux are stacks or aggregations of RBCs, which form because of the unique discoid shape of the cells. Thus, the correct answer is option B.
