Phagocytosis. Illustration of the process of phagocytosis, by which cells engulf solids (here, bacterial cells, orange). The bacteria are enclosed by an area of cell membrane as it enfolds or 'invaginates' to surround them (centre left). This invagination pinches off (upper right) to form an enclosed vesicle (lower right) within the cell cytoplasm (blue). Phagocytosis is a form of endocytosis. For three forms of endocytosis, see images C023/8787, C023/8789 and C023/8793. For exocytosis (the reverse process), see image C023/8796. For this artwork without labels, see image C023/8788.

RF2XANBYY–Illustration of three types of white blood cell: a macrophage (purple), dendritic cells (blue) and t helper cells (red). Macrophages mainly function to engulf and destroy substances which provoke an immune response. This process is known as phagocytosis. Dendritic cells' primary function is presenting antigens, which are molecules which the immune system recognises as foreign. T helper cells are involved in chemically signalling other immune cells and coordinating the immune response.

RF2XANC0K–Illustration of signal proteins called cytokines (red dots) and three types of white blood cell: a macrophage (purple, left), dendritic cells (blue) and t helper cells (purple, red nucleus). Macrophages mainly function to engulf and destroy substances which provoke an immune response. This process is known as phagocytosis. Dendritic cells' primary function is presenting antigens, which are molecules which the immune system recognises as foreign. T helper cells are involved in chemically signalling other immune cells and coordinating the immune response. They do so by releasing cytokines.

RF2XANBYX–Illustration of three types of white blood cell beginning an immune response: a macrophage (purple), dendritic cell (blue) and t helper cells (red). The T helper cells have released signalling proteins called cytokines (numerous red spheres) which attract other immune cells and coordinate the inflammatory response. Macrophages mainly function to engulf and destroy substances which provoke an immune response. This process is known as phagocytosis. Dendritic cells' primary function is presenting antigens, which are molecules which the immune system recognises as foreign.

RF2XANBYR–Illustration of three types of white blood cell responding to infection by bacteria (green): macrophages (purple), dendritic cells (blue) and t helper cells (red). The T helper cells have released signalling proteins called cytokines (numerous red spheres) which attract other immune cells and coordinate the inflammatory response. Macrophages mainly function to engulf and destroy substances which provoke an immune response. This process is known as phagocytosis. Dendritic cells' primary function is presenting antigens, which are molecules which the immune system recognises as foreign.

RF2BNNFJD–Illustration of a macrophage white blood cell (pink) engulfing coronavirus particles (orange). This process is called phagocytosis. Macrophages are cells of the body's immune system. They phagocytose (engulf) and destroy pathogens, dead cells and cellular debris. The coronavirus particles have been tagged by antibodies (white) to signal to the macrophages to destroy them.

RF2XANC04–Illustration of a macrophage (purple). Macrophages are white blood cells which mainly function to engulf and destroy pathogens, dead cells, cancerous cells, cellular debris and other substances which provoke an immune response. This process is known as phagocytosis.

Macrophages are white blood cells which mainly function to engulf and destroy pathogens, dead cells, cancerous cells, cellular debris and other substances which provoke an immune response. This process is known as phagocytosis.

RF2XANBYN–Illustration showing a type of white blood cell called a macrophage (purple) which has engulfed a bacterium (green) in a process called phagocytosis. Once bacteria or other foreign substances are detected in the body, macrophages are signalled. Macrophages engulf the bacteria and enclose them within a fluid-filled sac known as a vacuole (centre-right). Another organelle, the lysosome (top left), then releases enzymes known as lysozymes (pink) into the vacuole. The lysozymes break down the bacterium, rendering it harmless.
