ANATOMY

Detailed explanation-1: -White blood cells are called soldiers of the body, becauseThe white blood cells provide immunity to our body. They help in fighting against diseases, infections, allergies and foreign particles. These cells keep our body safe and healthy, much like the soldiers of a nation.

They are found in blood and the lymphatic system. They are the first to act in case of an infection and thus are referred to as soldiers of the human body.

Detailed explanation-4: -Etymology. The name “white blood cell” derives from the physical appearance of a blood sample after centrifugation. White cells are found in the buffy coat, a thin, typically white layer of nucleated cells between the sedimented red blood cells and the blood plasma.

Detailed explanation-5: -The human dermis is rich in leukocytes such as dendritic cells (DCs), macrophages (M), and T cells. Skin DCs migrate to lymph nodes to activate naive T cells, but there is evidence to suggest that skin DCs and M may also interact with memory T cells in situ (Tomura et al., 2010; Jiang et al., 2012).
