Cells that identify pathogens and distinguish one from another are called antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B cells. These cells play a key role in activating the immune response by presenting antigens to other immune cells, like T cells, to initiate a targeted immune response against the specific pathogen.
White blood cells: Destroys foreign materials. Red blood cells: transport oxygen throughout the body.
No blood cells- avascular
Glycoproteins and glycolipids serve as identification tags in the glycocalyx. These molecules help the body distinguish between its own cells and foreign or diseased cells by interacting with immune cells and other cells in the body. The unique patterns of sugars on these molecules are recognized by the immune system, allowing for proper immune responses.
In a biological context, differentiated cells have specific functions and structures that are suited for their role in the body, such as muscle cells or nerve cells. Undifferentiated cells, on the other hand, are primitive cells that have the potential to develop into various cell types, like stem cells.
