Immune System
It consists of tissues, cells, soluble molecules like antibodies and lymphoid organs. The WBC cells called the leucocytes have a significant role as they seek out to destroy the disease-causing organisms. These leucocytes are stored in different locations in the body including the spleen, bone marrow, and thymus. These organs are called as the lymphoid organs.
