  • T-cells recognize the antigens presented by phagocytes.
  • Phagocytic cells, such as neutrophils and macrophages, perform phagocytosis.
  • Phagocytosis plays a crucial role in the adaptive immune system by processing and presenting antigens to T-cells.
  • Phagocytosis occurs in various parts of the body, including the lymph nodes, spleen, and other lymphoid tissues.

Functions of Thymus Gland
