A series of phagocytic cells in the body, found especially in bone marrow, lymph nodes, liver and spleen, which attack and destroy bacteria and form antibodies.
Unit of the body made up of phagocytic cells (e.g., Kupffer cells of the liver, macrophages, and cells of the spleen and bone marrow) and functioning in immune responses to infection and in ridding the body of cellular debris.
The collective, coordinated action of phagocytes in the liver, lungs, lymph nodes, and spleen that engulfs foreign substances in the body.
A community of cells (phagocytes) spread throughout the body. It includes macrophages and monocytes. The RES is concerned with defense against microbial infection and with the removal of worn-out blood cells from the bloodstream.
This consists of highly specialized cells scattered throughout the body, but found mainly in the spleen, bone marrow, liver, and lymph nodes or glands. Their main main function is to engulf dying and dead red blood cells and the conversion of haemoglobin to bilirubin. They are also able to ingest bacteria and foreign colloidal particles.
Old name for the system of monocytes, macrophages, and dendritic phagocytes and antigen-presenting cells found in the blood and lymphoid tissues. This system is now called the mononuclear phagocytic system.
A network of cells located in the spleen, lymph nodes, liver, and bone marrow, responsible for blood cell production, bile formation, iron and blood pigment metabolism, and the breakdown of old blood cells.
